In order to avoid damage to machinery and danger to workers when changing or removing bearings, proper protective equipment and bearing removal equipment should be used.
Generally speaking, reuse of bearings is not recommended. If you are considering the reuse of a bearing, please read carefully Section 2, “Bearing Mounting.”
The process mentioned therein will need to be performed in reverse when removing the bearing. In this situation, maximum care must be taken not to effect the performance of the bearing during the removal process.
If a bearing which is press fit onto a shaft is removed by applying force to the outer ring, reuse of the bearing is not recommended.
