摘要： A bearing device is provided in which a contact portion between centering plates of an outer sleeve and a housing would neither be abraded nor deformed and which is superior in practicality, reduction of weight, durability and mass production even if the housing is made of synthetic resin and light in weight. The bearing device includes the housing (2) into which an outer sleeve (1) is inserted and a shaft (3) inserted into the outer sleeve (1). The housing (2) with the outer sleeve (1) is slidable in a linear relative to the shaft (3). The outer sleeve (1) has a ball endless recirculation path defined by a loading portion and a non-loading portion. Balls (5) are arranged in the ball endless recirculation path from a retainer (4). Centering plates (6) which may move finely are provided in the outer sleeve (1). The housing (2) is made of synthetic resin and a portion with the centering plates (6) are brought into contact when the outer sleeve 1 is mounted on the housing (2) is made of anti-abrasion material (7) such as metal.
