Self-aligning ball bearing with tapered bore
They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
Self-aligning ball bearings, with a tapered bore, have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. The tapered bore facilitates ease of mounting via adapter sleeves or withdrawal sleeves.
- Ease of mounting via adapter sleeves or withdrawal sleeves
- Accommodate static and dynamic misalignment
- Excellent high-speed performance
- Excellent light load performance
- Low friction
