Replacing a bearing

When the bearing of the NTN bearing unit is inoperative due to any faults, replace the bearing alone. The housing can be reused.

Note that replacing the bearing unit or parts with non-NTN products will void the warranty.

The replacement procedure

  1. First, fully tighten the set screws to prevent them from being caught on the bearing housing when the bearing is tilted.
  2. Next, insert the handle of a hammer into the bore face of the bearing, and pry the bearing open with the handle of a hammer. If it is completely tilted to 90°, draw it out on the cutout side of the housing. To fit a new bearing to the housing, perform the procedure above in reverse order.
