The new drylin® Q sliding plates have been developed for parts as varied as square tube in tube adjustments, for U-profiles or low-profiles. Lubrication-free robust linear movement is executed by sliding plates made of the high-performance polymer iglidur® J. The tolerance of the lifting column elements is compensated by means of a clever adjustment mechanism. Because first is the easy installation and then the patented adjustment of the sliding plate from the outside via an adjustment key. The drylin® Q sliding plates are used for such purposes as a cost-effective guide in lifting columns.
