If bearings are to be used again after dismounting, the force used to dismount them must never be applied through the rolling elements.
With separable bearings, the ring with the rolling element and cage assembly can be removed independently of the other ring. With non-separable bearings, the ring having the looser fit should be withdrawn from its seat first. To dismount a bearing with an interference fit, the tools described in the following section can be used. The choice of tools depends on the bearing type, size and fit. In the following, the bearing size is categorized:
- small → d ≤ 80 mm
- medium-size → 80 mm < d < 200 mm
- large → d ≥ 200 mm
