Double Row Angular Contact Ball Bearings

PMK Double Row Angular Contact Ball Bearings combine the load-handling advantages of paired single-row bearings in a compact unit. These bearings support high radial and axial loads in both directions, ensuring rigidity and smooth operation even under demanding conditions.

Their symmetrical design provides stable running accuracy and eliminates the need for separate matched pairs, reducing installation space and cost.

Key benefits

Supports axial loads in both directions with high radial capacity.
Compact design replaces two single-row bearings.
High rigidity and resistance to misalignment.
Reliable operation at high speeds.
Reduced installation time and simplified mounting.

Applications

Electric motors and gearboxes.
Automotive wheel hubs and transmissions.
Industrial machinery and conveyor systems.
Pumps, compressors, and high-precision assemblies.
