Check Compatibility Before Ordering
Confirm that the inner diameter, outer diameter, width, and shield configuration match your existing bearing. Bearings with identical dimensions may have different internal clearances or operating requirements.
Installation Note: Use the appropriate bearing installation method for your machine. Avoid transferring installation force through the bearing balls, as this can damage the bearing.
