Series SJP Rail Bearing Slide Offers Compact Precision
PHD will soon release its NEW Series SJP Slide product family. The Series SJP Slide features rail-bearing technology to provide smooth, precise linear motion. The unit's compact design accommodates applications within confined spaces.
The unit is available in three bore sizes (8, 12, and 16 mm) with a choice of three travel lengths each to fit a wide range of applications. Standard internal shock pads eliminate metal to metal contact reducing noise and end-of-travel impact forces.
Metric mounting holes and pattern provide an exact drop-in replacement to a competitor's unit providing an MRO replacement. The Series SJP Slide body incorporates twin switch slots on either side for convenient mounting of PHD's Reed and solid state switches. Series SJP Slides can also be fitted with certain competitor's switches providing even more versatility. Ask a local PHD distributor or call PHD directly for details.
