Compact Rail Plus linear guides have double-row ball bearings for higher load capacities, new robust steel sliding guides with longitudinal protection and floating wipers. By combining two rails with different runners, self-aligning systems can be created which can compensate for alignment errors in two planes: axially up to 3.5 mm and radially up to ±1.3°.
PR/PNR rail (Rollon TG/TMG): C profile rail with convex inner raceways, made of cold drawn carbon steel.
RPF guiding sliders (Rollon RV): Can support loads and moments in all directions, especially in radial direction.
RPL floating sliders (Rollon RP): Can move easily axially and rotate easily in Mx without affecting preload and smoothness.
RPE extra-floating sliders (Rollon RU): Can move completely axially and rotate easily in Mx without affecting preload and smoothness.
RPK rotating sliders (Rollon RA): These runners consist of fixed and floating bearing rollers. They can carry the full radial load and guide the payload during the movement. The rollers can rotate easily in Mx without affecting the preload and the running smoothness. These rotors compensate for angular errors in the mounting surfaces.

Comments
- It is possible to create self-aligning systems F+L / R+D or K+L / K+E (Rollon V+P / V+U o A+P / A+U) to compensate for inherent misalignment of the mounting surfaces.
- Robust RP...O rotor (Rollon RD) in steel with double row ball bearings, lateral seals and floating wipers. Also available in RP...P version with mounting holes parallel to the main load direction.
- Various anti-corrosion treatments available for rails and rotor bodies: zinc plating according to ISO 2081 (standard for rail size 28-43 and all rotor bodies), Rollon-Nox (standard for rail size 18), Rollon Aloy, Rollon E coating and nickel plating.
- Compact dimensions due to the C-profile, which contains the runners and rollers.
- Induction hardened and ground raceways (sizes 28-42)
- Nitrided, black oxidised and polished raceways (size 18)
- Adjustable preload.
