Application overview
How NSK bearings are specified for Automotive Aftermarket
The right NSK bearing for this application is defined by its full part number, its position in the assembly and its exact execution, not by bore and outside diameter alone. Feed Mechanisms Company supplies genuine NSK bearings matched to that complete specification.
Automotive repair and parts buyers replace wheel hub bearings, tapered roller wheel bearings, needle bearings in transmissions, and bearings in AC compressor clutches. Wheel and compressor bearings run with road contamination, heat and constant load cycles. Buyers need the exact reference for the vehicle position, with correct seals and dimensions, so parts fit straight away.
- Identify hub bearings by the full DAC-style reference and vehicle position, because similar dimensions can have different seal or ABS configurations.
- Order tapered roller wheel bearings as matched cone and cup sets for each axle position.
- Confirm sealing and grease specification for AC compressor clutch bearings, which run hot and continuously under the bonnet.
- List front and rear, left and right positions separately when ordering for repair batches.
