Installation Procedure

1. Ensure the shaft and housing bore are clean and free of debris. Verify dimensions match bearing specifications. 2. Carefully press the bearing onto the shaft or into the housing, applying even pressure to the ring being fitted. Avoid striking the opposite ring. 3. Confirm the bearing rotates freely without binding after installation.
