A Shim is used in a roller bearing to adjust the internal clearance or preload within the bearing to achieve proper performance and minimize friction and wear. They can be positioned between the inner and outer bearing rings or between rolling elements to control axial or radial clearances.Attributes:• Ensures that the bearing operates within the specified tolerances• Help reduce vibrations and noise generated by the bearing Applications:A Shim is used in wheel bearings to adjust the internal clearance, ensuring proper alignment.
