A self-aligning spacer assembly includes a pair of sleeves having end faces held in mutually abutting relationship by a resilient collar. One of the abutting end faces has a convex spherical shape and the other is conical to provide substantial line contact between the faces. One of the sleeves has an internal diameter such that it fits snugly on a shaft or arbor on which the spacer assembly is mounted, an the internal diameter of the other sleeve is slightly greater so that it can rock on the arbor to a limited extent relative to the other sleeve.
