that the bearing on the opposing end is not damaged during assembly.

SEAL INSTALLATION RECOMMENDATIONS
1. Check Seal – for damage that may have occurred prior to installation. A sealing lip that
is turned back, cut or otherwise damaged should be replaced.
2. Check Bore – to see that leading edge is deburred. A rounded corner or chamfer
should be provided.
