Series of linear axes extended

16 November 2007

Schunk has added size 60 to its Beta series of linear axes, thereby providing even finer graduation in its program of precise linear modules. An important prerequisite for selecting the best axis in terms of cost and performance, the Size B 60 is intended for economical axis applications with high demands on dynamic and smooth running.

It features a precise profiled rail guide and can be operated both by a ball-screw spindle drive with supports and by a robust, play-free toothed-belt drive with adjustable belt tension. As both the ball screw drive and the profiled rail guide have been generously dimensioned, size B 60 has a small profile that is characterised by high load-bearing capacity and a long operating life.

The version with ball screw drive is designed for a high driving force of 4,000N and attains travel speeds of up to 2.5m/s, with a maximum stroke of 5,120mm thanks to the spindle supports which reduces spindle flexing. Acceleration values of up to 20m/s² are possible with a repeat accuracy of +/- 0.03mm. By comparison, the version with toothed belt drive attains a high driving force of 850N and covers distances up to 7,620mm at speeds of up to 5m/s. The maximum possible acceleration is 30m/s² with a repeat accuracy of +/- 0.08mm.

Short or long slide plates measuring 180 or 230mm in length are optionally available for both versions, and both versions are also protected against pollution by a covering band that passes through the axis carriage. Each version is powered by a servo-motor that is connected to the axis via a flange and a coupling.
