Design Features of SFRW166zz Bearing
SFRW166zz Bearing is designed to provide enhanced shaft support and improved alignment. SFRW166zz bore dia is 0.1875″. Its out dia is 0.375″. SFRW166zz flange outer dia is 0.422″ and its flange thickness is 0.031″. SFRW166zz inner ring outer dia is Inner_Ring_0.375″ 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 SFRW166zz Bearing Provide?
- Enhanced Axial Load Support: Due to the extended inner ring, SFRW166zz 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 SFRW166zz Bearing Be Used for?
SFRW166zz 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
