Precision of SKF Bearing

The BS series of super-precision, angular-contact, thrust ball bearings have static load ratings up to 245 kN, fatigue load limits up to 9.15 kN, and top speeds up to 17,000 rpm to provide axial guidance of shafts for machine-tool applications. The have a 62° contact angle and polyamide 66 bearing cages. They are filled with calcium-complex-soap grease based on ester/mineral oil which is retained with steel-reinforced, oil and wear-resistant acrylonitrile-butadiene rubber (NBR) seals that are good from –40 to +100°C. They come in matched sets of two, three, or four bearings or as single, universally matchable bearings.
