Anti-vibration linear motion guide unit

Abstract

An anti-vibration linear motion rolling contact guide unit includes a rail, a slider assembly, a plurality of rolling members interposed between the rail and the slider assembly to thereby provide a rolling contact between the rail and the slider assembly, and at least one anti-vibration block fixedly attached to one end of the slider assembly. The rail has a sliding guide surface and the anti-vibration block includes an anti-vibration mechanism which includes a friction member which is preferably provided with a contact sheet at its forward end and slidably fitted in a hole formed in the anti-vibration block. The friction member is biased toward the sliding guide surface of the rail by means of a biasing means which is also fitted in the hole. An adjusting screw is screwed into a threaded portion of the hole so as to adjust the location of the biasing means which is in contact with and thus applies a force to the friction member. With this structure, any vibration between the rail and the slider assembly can be advantageously absorbed.
