Patent ID: 8882354

Claim:
A tolerance ring comprising: an annular band formed from a metallic material wherein the metallic material consist of a sheet comprising a plurality of circular perforations, the circular perforations evenly distributed across the sheet and the sheet shaped to include a sheet profile, the sheet profile including waves, cones, or ball shapes, wherein the annular band is located completely within a low friction layer such that no portion of the annular band is exposed from and external to the low friction layer; an elastomeric layer on the annular band; and the low friction layer on at least one of the annular band and the elastomeric layer, wherein the low friction material comprises a polymer selected from the group consisting of a polyketone, a polyaramid, a thermoplastic polyimide, a polyetherimide, a polyphenylene sulfide, a polyethersulfone, a polysulfone, a polyphenylene sulfone, a polyamideimide, ultra high molecular weight polyethylene, a fluoropolymer, a polyamide, a polybenzimidazole, and any combination thereof.
