Single Direction Angular Contact Thrust Ball Bearing
PMK Single Direction Angular Contact Thrust Ball Bearings are designed to support high axial loads along with limited radial forces in one direction. The angular contact arrangement provides increased stiffness and accurate positioning under combined loading.
Key benefits
- Supports high axial load in one direction.
- Increased axial stiffness through optimized contact angle.
- High-speed performance with minimal friction.
- Compact structure suitable for precise alignment systems.
- Separable design for simple installation and maintenance.
Applications
- Machine tool spindles and feed mechanisms.
- Turbine and compressor shaft assemblies.
- Precision rotary tables and indexing systems.
- Actuators and control valves requiring high positioning accuracy.
