ABSTRACT:
Spacer rings of a form-memory alloy, alternatively known as memory metals, are used in the form-locking or fastening of bearings on shafts and in housings. Radial or axial expansion when the critical A.sub.S temperature of the alloy is exceeded results in firm clamping in the direction concerned. The use of alloys with a one-way characteristic allows the bearing, after heating, to remain in operable condition at all operating temperatures.
