Single Direction Tapered Roller Thrust Bearing

PMK Single Direction Tapered Roller Thrust Bearings are designed for high axial load capacity in one direction. The tapered geometry of the rollers allows uniform load distribution and precise axial positioning under heavy thrust loads.
These bearings exhibit high rigidity and efficient load transfer, making them ideal for supporting axial forces in rotating assemblies.
Key benefits
- Supports very high axial loads in one direction.
- High rigidity and precise axial positioning.
- Tapered roller geometry ensures stable load distribution.
- Low friction and consistent rotation under thrust.
- Separable parts simplify assembly and maintenance.
Applications
- Vertical shaft assemblies and screw presses.
- Marine propulsion and heavy machinery.
- Rolling mill screw-down mechanisms.
- Industrial gearboxes and compressors.
