LINEAR RAIL RANGE Linear Roller System with MR rail and R, R.T, R.S sliders The MR Series Linear Rail System consists of a C-section steel rail with internal convex raceways, where robust double row ball bearing rollers travel. The high precision rollers are lubricated for life and protected with 2RS seals. Sliders are available with three or five rollers, including eccentrics to adjust the bearing preload. Both ends of the sliders are equipped with polyamide wipers to remove debris from the raceway and grease impregnated felt wipers to lubricate the raceways for long life with minimal maintenance. The MR rail system is especially equiped for harsh environments where contamination is a problem. Most bearing systems utilize a groove that a roller or ball travel within. These grooves capture and hold debris that eventually cause the bearing to fail. The convex raceway of the MR Series provides a place for debris and other contaminates to be pushed aside by the rollers. This feature enables the MR Series to function in environments where other bearings quickly fail. R.T Sliders Series are made of zinc plated steel with mounting holes perpendicular to the roller axis and parallel with the direction of preferred loading. The sliders have sealed rollers and axial wipers for protection of the internal parts. The R.T Series Sliders are available in 2 sizes and with either 3 or 5 rollers R Sliders Series are made of zinc plated steel with mounting holes parallel to the roller axis and perpendicular to the direction of preferred loading.The sliders have sealed rollers, axial wipers, and longitudinal seals for optimal protection of the internal parts and a sealing strip to prevent accidental tampering of the fixed rollers. The R Series Sliders are available in 3 sizes and with either 3 or 5 rollers. The R.S Sliders Series have a very slim body to obtain the most compact slider possible, without sacrificing performance. They also offer both threaded and through hole mounting options. The standard slider body is made from zinc plated steel but is also available in all Stainless Steel construction for higher corrosion resistance. The R.S Series Sliders are available in 2 sizes, 2 materials, and with either 3, 4 or 5 rollers.

Sliders are available with either 3 or 5 rollers. For the 3 roller version, the first and third roller are fixed, concentric rollers that run on the same raceway. The second roller is eccentric and runs on the opposite raceway. The eccentric feature is used to adjust the slider preload in the rail. For the 5 roller version, the two lateral and the central roller are fixed, and run on the same raceway. The second and fourth roller are eccentric and run on the opposite raceway. The eccentric feature is used to adjust the slider preload in the rail. Because one raceway contacts more rollers than...

R. rollers for MR, FXR rails LINEAR RAIL RANGE The ROLLERACE rollers are designed around a double-row precision ball bearing to guarantee both high radial and axial load capacities. The rollers are protected by a double lip sealing system (2RS) to assure long lifetime, even in difficult environments. The integrated roller pivot has concentric or eccentric shape, to allow for preload setting in the different systems. The bearings are made to precision class DIN620 of core-hardened carbon steel. The rollers are available in series R.V with 2 contact points on the protruding raceways to obtain, a...
