FRW188
Design Features of FRW188 Bearing
FRW188 Bearing is designed to provide enhanced shaft support and improved alignment. FRW188 bore dia is 0.25″. Its out dia is 0.5″. FRW188 flange outer dia is 0.547″ and its flange thickness is 0.023″. FRW188 inner ring outer dia is Inner_Ring_0.5″ and its inner ring width is 0.1562″. The flange and extended inner ring work together to limit axial movement and keep the bearing in place.
What Benefits Can FRW188 Bearing Provide?
- Enhanced Axial Load Support: Due to the extended inner ring, FRW188 bearing can manage higher axial loads.
- Augmented Rigidity: This bearing assembly gains additional stability from the extended inner ring.
- Simplified Mounting: The extended inner ring facilitates easier mounting.
- Better Alignment: The extended inner ring allows for improved alignment within the application.
What Can FRW188 Bearing Be Used for?
FRW188 Bearing is especially useful in applications where axial loads or vibrations are present, such as:
- Automotive Transmissions
- Electric Motors
- Robotics
- Conveyor Systems
- Pump and fan installations
