Linear bearing with integrated cage assist

The RN linear guideway / cross-roller guideway is the advanced development version of the R linear guideway. Efficiency is greatly increased without the need for larger installed dimensions thanks to the larger contact surface between rollers and guideway. This guideway features three times more load capacity, high rigidity and precision, as well as the reduced contamination risk due to the narrow gap between the guide rails.

Linear bearing type RN

Sizes: 3, 4, 6, 9, 12

Lengths: 50 to 1500 mm


  • KBN, KBS cage
  • GA and GAN end screws
  • GD special fastening screws
  • FORMULA-S cage controls


The robust, simple design of the FORMULA-S cage control, consists of only a few components and meets all requirements in terms of productivity and cost-effectiveness. The sophisticated design means it can be easily integrated into existing constructions. FORMULA-S works in any installation orientation regardless of the preload of the guideway.


 The advantages of cage control include trouble-free operation, high acceleration, and no readjustment of the cage. Furthermore, the shape and position tolerances of the surrounding structure or temperature differences do not lead to cage creep. All in all, an excellent basis for a long service life.
