Design Features
- Special design angular contact ball bearings in back-to-back (DB) arrangement
- With ring guided resin or machined brass cage
- Non-contact seal on one side (of each bearing)
- With 35° contact angle
- With P5 accuracy
- Available for bore diameters from 130, 170, 220, 340 and 400 mm
Operating Benefits
- Compact, space-saving design, with a 35% thinner profile than standard angular contact ball bearings
- High accuracy with low NRRO: 0.5μm or lower was achieved with BRSA130
- High moment stiffness on par with crossed roller bearings
- Lower torque than roller bearing alternatives
