Features and Specifications

  • Incorporates pre-loaded linear bearings type RSD and double-sided track-rail, including roller cages.
  • Slide-top and -base have equal lengths.
  • 2 standard strokelengths (N- and L-stroke). Linear strokes are limited by internal mounted end-stops, two in the slide-top and one or two in the base-plate, depending on RTLA or RTNA version. N-stroke: for normal stroke/travel, with normal loads. L-stroke: for longer stroke/travel, with reduced loads.
