Abstract

An annular collar includes a first clamping surface to be positioned radially outwardly of a surface of a bearing inner ring. The annular collar is made of a thermoelastic material such that an increase in temperature decreases the circumference of the annular collar and causes the first clamping surface to clamp against the surface of the bearing inner ring. The thermoelastic material may be a shape memory alloy or a polymer.
