1. A system for elastically compensating for wear and misalignment, comprising:
- a housing having a bore;
a pin located in and coaxial with the bore of the housing;
a ring located between the housing and the pin in the bore of the housing, the ring comprising;
a backing layer;
an expanded grid structure having a plurality of openings, formed from at least one of a stretched metal, expanded metal, metal alloy, plastic material and woven or nonwoven mesh, and the expanded grid structure having a wave-like configuration with strands protruding as bulges out of a plane thereof to form a pattern of waves and bow springs to provide elastic deformation under load;
a layer laminated into the openings of the expanded grid structure; and
at least one layer of adhesive for bonding the backing layer, expanded grid structure and layer together to provide elastic deformation of the ring between the housing and pin, wherein the ring comprises one of a bushing, a bearing and a tolerance ring, and the at least one layer of adhesive comprises a pair of layers of melt adhesive that penetrate through the expanded grid structure and immerse sides of the expanded grid structure to both the backing layer and the layer.

Abstract
A system for elastically compensating for wear, thermal expansion and misalignment comprises a ring located between a housing and a pin in the bore of the housing. The ring has a backing layer, an expanded grid structure having a plurality of openings, a low friction layer penetrated into the openings of the expanded grid structure, and adhesive for bonding the backing layer, expanded grid structure and low friction layer together to provide elastic deformation of the ring between the housing and pin.
