5 Features of LB203245 linear bushings

Low friction linear motion: steel balls are accurately guided by a retainer, so low frictional resistance and stable linear motion can be achieved.

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.
