Technology
Cup & Cone Bearing
Angular contact bearings of the cup & cone type offer greater strength than sealed cartridge industrial bearings due their ability to displace lateral and vertical loads more effectively for super smooth rotation and longer durability. Angular contact bearings also allow easier maintenance, adjustability and serviceability.
