Cylindrical Roller Thrust Bearings

PMK Cylindrical Roller Thrust Bearings are engineered to carry heavy axial loads in one direction with minimal axial displacement. The line contact between the rollers and raceways allows these bearings to handle extremely high thrust forces with excellent stiffness and low friction.

They are suitable for applications requiring high axial load capacity, precise guidance, and compact axial installation.

Key benefits

Extremely high axial load capacity due to cylindrical roller line contact.
High stiffness and precise axial guidance under load.
Low friction and heat generation at high thrust speeds.
Compact design suited for limited axial space.
Separable components allow easy mounting and servicing.

Applications

Gearboxes and vertical shafts.
Extrusion presses and rolling mills.
Marine propulsion and heavy-duty drives.
Machine tool and mechanical press assemblies.
