Single Direction Thrust Roller Bearing

PMK Single Direction Thrust Roller Bearings are engineered to support heavy axial loads in one direction while maintaining precise shaft alignment. They are typically used in vertical or high-thrust assemblies requiring high rigidity and low friction.

Key benefits

Supports heavy one-directional axial loads.
Compact design with high load-bearing rollers.
High axial rigidity and low starting torque.
Separable components simplify mounting and servicing.
Designed for long operating life under continuous thrust.

Applications

Vertical shafts and screw presses.
Machine tool spindles and heavy industrial drives.
Marine propulsion and gear systems.
Rolling mill and turbine assemblies.
