My iglidur plain bearing has become jammed on the shaft. What to do?

Jammed plain bearings can have different causes such as housing holes with insufficient tolerance, as a result of which compression of the bearings and thus reduction of the inner diameter occurs. Another reason that is often observed is an insufficiently deburred hole. If the bearing is press-fitted carelessly, even small pieces of material residue can come between the hole and the plain bearing or cause damage to the bearing. Expansion or contraction of the material as a consequence of temporary or long-term temperature effects can also cause jamming. In this case, it is important to pay special attention to the materials used and the tolerances allowed and, if necessary, to ensure greater bearing clearance or the use of other materials.
