Double Direction Thrust Ball Bearings

PMK Double Direction Thrust Ball Bearings support axial loads in both directions, providing smooth and accurate rotation under low to moderate speeds. Designed for applications with bidirectional thrust, these bearings ensure balanced load sharing and minimal axial play.
Key benefits
- Handles axial loads in both directions.
- Low friction and smooth rotation for precise positioning.
- Compact, high-accuracy design for limited axial space.
- Simple, separable structure for ease of assembly.
- Suitable for moderate-speed applications with light radial load.
Applications
- Machine tool tables and vertical shafts.
- Precision rotary systems and gearboxes.
- Compressors, pumps, and turbines.
- Measuring instruments and light mechanical assemblies.
