Seal improves performance of mounted tapered roller bearing

SKF has vastly extended the performance, and product life, of its new mounted tapered roller bearing by pairing it with a superior seal.

The mounted tapered roller bearing, also known as a Type E bearing, incorporates SKF’s CR Seal. This extends service life by virtually eliminating ingress of contamination, even under harsh conditions.

“In mud-slurry tests, our seal withstood more than 600 hours with zero contamination ingress,” says Eric Brubaker, Director of Product Management at SKF North America. “Rival products saw ingress at 50 hours or earlier.”

The mounted tapered roller bearing is used when an increased thrust load is needed with limited axial movement. This makes it appropriate for demanding industries such as mining, aggregates and cement. Potential applications include material handling equipment, such as belt feeders and screw conveyors, and process machinery including grinders, shredders and mixers.

These units typically break down for one reason: seal failure. By improving seal performance, they can be designed to last much longer – extending uptime and increasing reliability.

CR Seals offer several lines of defence against contamination. The use of hydrogenated nitrile rubber (HNBR) resists both wear and high temperatures, while a full rubber outside diameter improves static sealing within the housing. Multiple sealing lips exclude all types of contamination including dirt, mud, water, sand, and powder. The seal also allows the bearing to be relubricated without risking damage to the sealing lips, says SKF.
