Jul 11, 2006 SKF® high-capacity cylindrical roller bearings feature low cross-section cage that eliminates risk of damage by roller-to-roller smearing. Cage design also increases lubrication by allowing room for oil passage, which lubricates contacts between rollers and raceways, provides cooling, and reduces risk of metal-to-metal contact. Optimized cross-sections of rings and rollers minimize potential for fretting corrosion, ring creep, and flange fracture.
