Single Row Angular Contact Ball Bearing

PMK Single Row Angular Contact Ball Bearings are designed for applications where combined radial and axial loads must be supported simultaneously. These bearings are built to operate at high speeds with precision alignment and minimal frictional loss.

The internal geometry allows higher axial load capacity in one direction, with contact angles optimized for stiffness and smooth motion. They are often used in pairs for bidirectional axial load capacity.

Key benefits

Supports both radial and axial loads in one direction.
High-speed capability due to optimized ball–raceway contact.
Excellent axial rigidity and precision alignment.
Can be mounted in matched pairs for bidirectional load handling.
Low vibration and quiet operation at high rotational speeds.

Applications

Machine tool spindles and high-speed drives.
Automotive transmissions and clutches.
Pumps, compressors, and blowers.
Electric motors and gearboxes.
