Self-aligning ball bearings use two rows of balls and a common spherical outer-ring raceway to accommodate angular misalignment while maintaining smooth rotation.
BWK supplies open, sealed and tapered-bore designs for fans, conveyors, textile machinery and transmission equipment where shaft deflection or mounting deviation may occur.
Key Advantages
1. Automatic Misalignment Compensation
The spherical outer raceway helps accommodate shaft deflection and housing alignment errors.
2. Low-Friction Double-Row Design
Two rows of precision balls support stable radial operation at practical industrial speeds.
3. Reliable Mixed-Load Performance
Suitable for radial loads with limited axial load in either direction.
4. Multiple Bore and Seal Options
Available with cylindrical or tapered bores, open construction or contact seals.
