Bearing device

A bearing device comprising a housing into which an outer sleeve is inserted and a shaft inserted into said outer sleeve, wherein said shaft and said housing with said outer sleeve are relatively slidable in a linear fashion, characterized in that said outer sleeve has a ball endless recirculation path defined by a loading portion and a non-loading portion, balls are arranged in said ball endless recirculation path by a retainer, centering plates for supporting said balls at said loading portion from the outside are floatingly movable in through-windows formed in said outer sleeve, said housing is a monolithic unit of synthetic resin having an inner surface that is substantially cylindrical in shape and hollow therethrough and capable of enclosing said outer sleeve within its inner surface, and an anti-abrasion material, is arranged within said housing between the opposing contact points of said centering plates and said housing.
