Abstract
An adjustable spacer with hardened end portions and a non-hardened intermediate portion therebetween is mountable between a pair of roller bearings also mounted on a shaft such an axle or spindle or the like. The hardened material contacts the faces of the roller bearings but helps prevent wear therebetween and unwanted movement of the bearings on the shaft. The unhardened material allows the spacer to collapse in the axial direction to maintain desired axial loads on the bearings.

A method of manufacturing an adjustable spacer comprising:
- forming an annular shaped adjustable spacer comprising a first end portion, a second end portion and an intermediate portion therebetween;
- and
- forming the first end portion and the second end portion of the annular shaped spacer of a hardened material, wherein said first end portion and said second end portion are harder than the intermediate portion and wherein the intermediate portion is more deformable than the first end portion to allow the intermediate portion to compress in an axial direction.
