Offered in a variety of sizes and types, SKF rolling bearings with integral seals provide solutions to protect against contaminants and retain lubricants. According to the company¡¯s press release, rolling bearings with integral seals provide the capability to simplify bearing arrangements and to ¡°drop-in¡± sealed bearings within existing envelopes. These bearings include shields, low-friction and contact types manufactured from nitrile rubber and selected based on friction and operating speed requirements.
The ¡°greased for life¡± pre-lubricated versions boast additional performance and service benefits by avoiding problems associated with the lubrication process. These problems include mixing greases or introducing contaminants. The pre-lubricated types with seals on both sides prevent over- or under-greasing, offer grease retention, and minimize maintenance requirements.
Integral seals can be incorporated in a wide range of types including deep groove, angular contact and self-aligning ball bearings as well as cylindrical, needle, spherical and toroidal roller bearings. Custom sealing solutions can be developed for particular application processes.
