reconditioning large rolling bearings rather than direct replacement, companies can save time and money, while ensuring that the bearings are restored to an acceptable, functionally reliable condition, says Dave Wall <p style="margin:0px 0px 10px;padding:0px;border:0px

The characteristics and condition of rolling bearings have a significant influence on the overall availability of plant and machinery. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida

However, many rolling bearings are still dismounted and replaced as part of a company’s routine maintenance activities, particularly on machinery that is deemed critical to the production process. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica

In many cases though, bearings can be restored to a completely acceptable, functionally reliable condition using appropriate cleaning and rework techniques. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue,

This is particularly true if the bearings are large, where reconditioning or rework can often save valuable time and money. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida

Reconditioning can offer significant advantages in applications such as paper mills, steel and aluminium processing, mining and quarrying, rail and marine, where large rolling bearings often play a critical role in keeping high value production plant, machines, ships and vehicles operating continuously and efficiently around the clock. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida

When considering reconditioning of rolling bearings, you don’t always need to approach the original manufacturer of the bearing. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida

Some bearing suppliers can provide reconditioning services for any bearing product, regardless of the manufacturer. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida

If you already have a good working relationship in place with a particular bearing supplier, it is worth asking if they can recondition other suppliers’ bearings too. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue,

of the cost <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida

Reconditioning or maintenance costs of a large rolling bearing typically amount to between 15% and 70% of the cost of a new bearing, depending on the extent of the reconditioning work involved. Average costs are around 50% of new purchases. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> In the UK, Schaeffler’s bearing reconditioning service normally involves an initial, free on-site inspection of the bearings in order to determine whether reconditioning is appropriate and possibly viable. This saves any unnecessary transportation and inspection costs being incurred by the customer. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida

An expert from a local Schaeffler Technology Centre in the UK will typically inspect the bearing damage on-site and record this by taking photos, which can be sent to specialists at Schaeffler’s Wuppertal repair centre in Germany. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida

A budget cost for reconditioning can then be provided to the customer, who can then decide whether to proceed with an in-depth damage diagnosis and reconditioning work. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue,

The initial on-site inspection allows Schaeffler to offer specialist advice and guidance to the customer on how the life of the bearings can be extended in the future. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue,

For example, by using advanced materials or coatings on certain bearing components. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida

On-site visual inspection by trained, experienced engineers can also help to discover other factors that may be causing the bearings to wear prematurely, such as incorrect bearing mounting, inappropriate lubrication or loading conditions. <p style="margin:0px 0px 10px;padding:0px;border:0px

In certain cases and after careful assessment and damage diagnosis, the customer may even receive the same warranty as for a new bearing. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> <strong style="margin:0px;padding:0px;border:0px currentColor;border-image:none;line-height:inherit;font-family:inherit;font-size:inherit;font-style:inherit;font-variant:inherit;font-weight:bold;vertical-align:baseline;font-stretch:inherit;">Reconditioning of TAROL bearing units <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> Schaeffler also offers rail operators a reconditioning service for its TAROL range of axlebox bearing units. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> The repair and periodic maintenance of axlebox bearing units on rail vehicles can significantly extend the life of these very heavily stressed components. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> As the reconditioning service is rapid, the customer benefits from minimal downtime. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> The reconditioning itself consists of thorough cleaning of all bearing components, as well as dimensional and functional inspection of the complete bearing unit. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> The axial clearance is readjusted and the bearings are relubricated.

Examples include the provision of threaded holes, adjustment of bearing clearance or changes to the bore diameter. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> A rolling bearing from replacement parts stock that is no longer required can be adapted to suit a different purpose. This saves time, material and cost, while still providing the customer with a rolling bearing that is of new quality. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> Coatings can also be applied in order to improve the characteristics of bearing components. A coating can prevent corrosion, reduce wear or contribute to energy efficiency by decreasing friction. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> If damage is discovered during examination of the rolling bearing, a request can be submitted for examination and assessment of this damage. The results can be recorded in an assessment report. This means a statistical evaluation of possible defect sources can be carried out. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> <strong style="margin:0px;padding:0px;border:0px currentColor;border-image:none;line-height:inherit;font-family:inherit;font-size:inherit;font-style:inherit;font-variant:inherit;font-weight:bold;vertical-align:baseline;font-stretch:inherit;">Environmental Protection <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> A decision in favour of reconditioning of rolling bearings allows manufacturing companies to make a considerable and ongoing contribution to reducing energy consumption and resources. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> In the case of defective components, Schaeffler ensures correct separation of materials according to grade. <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;text-transform:none;line-height:20.8px;text-indent:0px;letter-spacing:normal;font-family:"Helvetica Neue", HelveticaNeue, Helvetica, Arial, "Lucida Grande", sans-serif;font-size:16px;font-style:normal;font-weight:400;word-spacing:0px;vertical-align:baseline;white-space:normal;orphans:2;widows:2;font-stretch:inherit;background-color:#FFFFFF;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;font-variant-numeric:inherit;font-variant-east-asian:inherit;"> Dave Wall is Senior Applications Engineer at <a style="font:inherit;margin:0px;padding:0px;outline:0px;border:0px currentColor;border-image:none;color:#1D4B7B;text-decoration:none;vertical-align:baseline;font-size-adjust:inherit;font-stretch:inherit;" href="https://www.schaeffler.co.uk/" target="_blank"><strong style="margin:0px;padding:0px;border:0px currentColor;border-image:none;line-height:inherit;font-family:inherit;font-size:inherit;font-style:inherit;font-variant:inherit;font-weight:bold;vertical-align:baseline;font-stretch:inherit;">Schaeffler UK</a>.
