Recirculating linear ball bearing
AST Bearings

AST's Linear Bushing products are high precision linear motion rolling guides which travel along shafts to achieve endless linear motion. In the external cylinder, a retainer, steel balls, etc. are compactly incorporated.

Low Frictional Linear Motion - Steel balls are accurately guided by a retainer so that low frictional resistance and stable linear motion can be achieved.

Wide Selection - For each dimensional series, standard, adjustable clearance and open types are available with and without seals, so the best linear bushing for the application may be selected.

Stainless steel Available - Linear Bushings made of stainless steel are also available. This type is suitable for applications where corrosion resistance is important.

Simple Replacement Of Conventional Plain Bushings - It is easy to use Linear Bushings instead of conventional plain bushings, because both types are used with a round shaft, and no major redesign is necessary.

A wide variety of sizes are available from AST for virtually every application (special orders also available).
