Linear bearing type RN
The RN linear bearing represents a consistent optimization of the R linear bearing. Thanks to the enlarged contact surface of the roller with the guideway, the performance capacitiy is significantly increased, with unchanged fitting dimensions.
The features of the RN include:
– approx. 3x higher load carrying capacity
– significantly reduced susceptibility to cage drift
– reduced danger of contamination due to narrower gap between individual guides

Cage control FORMULA S from SCHNEEBERGER
The cage control system FORMULA S completely fulfils these requirements in terms of productivity and economic efficiency. It is extremely robust, easy to assemble and consists of only a few components.
FORMULA S is based on the dimensions of our proven RN and RNG ranges. Its clever design means it is easy to incorporate into your existing construction. Above all: FORMULA S works in any mounting position, regardless of the bearing’s preload.
Advantages
- Smooth, trouble-free operation and therefore a more productive period of use High acceleration allows distances to be travelled quickly and therefore reduces cycle times
- No readjustments to the cage, not even for vertical installation
- Geometric tolerances in the surrounding construction or differences in temperature do not lead to instances of cage creeping
- Long operating life
