Installation Procedure

1. Thoroughly clean the bearing housing and shaft to remove any debris or lubricant residue. 2. Carefully align the bearing with the shaft and housing, ensuring no angled insertion. 3. Apply even pressure to the outer ring to press the bearing into the housing, or to the inner ring to press it onto the shaft, avoiding impact forces.
