Sealmaster offers paver bearings designed to withstand abrasive paving conditions and asphalt materials. A four-barrier seal technology protects the bearing¡¯s inner components from contaminants. The barrier, comprising a ductile iron end cap, rotating shield, self-adjusting washer and high-temperature seal, keeps asphalt from forcing its way into the bearing, filters out asphalt particles, withstands high temperatures, and resists asphalt erosion. "Today¡¯s asphalt materials can cause serious damage to bearings, but seal technology gives Sealmaster paver bearings longer life and better performance, " says Kevin Mues, senior staff engineer for Paver Bearings, Emerson Power Transmission. According to the company¡¯s press release, each Sealmaster paver bearing features a heavy-duty housing and high-strength, brass retainer. Factory lubrication is chosen to best fit bearing operation conditions.
