Single Row Tapered Roller Bearings

PMK Single Row Tapered Roller Bearings are engineered to support combined radial and axial loads, with the load transmitted through the tapered rollers at an angle relative to the bearing axis. This geometry allows them to accommodate high axial forces in one direction while maintaining rigidity and precise alignment.

These bearings are separable, with the cone (inner ring with rollers) and cup (outer ring) capable of being mounted individually.

Key benefits

Supports high radial and single-direction axial loads.
High stiffness and low friction ensure efficient torque transmission.
Adjustable internal clearance allows preloading for higher rigidity.
Simple separable design for easy mounting and maintenance.
Available in metric and inch sizes to suit global applications.

Applications

Automotive wheel hubs and transmissions.
Machine tool spindles and gearboxes.
Agricultural, construction, and mining equipment.
Heavy-duty industrial drives and powertrains.
