Compact Rail Plus Series linear guides feature double-row ball bearings for higher load ratings, rigid rails with convex raceways and new robust steel runners with longitudinal protection and movable wipers. Compact Rail Plus is designed for the most demanding applications in terms of load capacity, dynamics and working environment. The self-alignment capability has been retained, making this product family unique. The sliders are available in four versions: fixed bearing (RV), floating bearing (RP), extra floating bearing (RU) and compensating (RA). * Available in 3 different sizes: 18, 28, 43 mm. * Self-aligning systems (V+P / V+U or A+P / A+U) can be implemented to compensate for existing misalignment of the mounting surfaces. * If necessary, a lack of precision in the parallel alignment of the mounting surfaces of the linear rails can be compensated. * Rugged steel RD runners with double row ball bearings with side seals and movable wipers. Also available in the RD version with mounting holes parallel to the main load direction. * Various anti-corrosion treatments are available for rails and runners: Galvanized to ISO 2081 (standard for rail size 28-43 and all runner bodies), Rollon-Nox (standard for rail size 18), Rollon Aloy, Rollon E-Coating and nickel plated. * Compact dimensions due to the C-profile that contains the runners and roller elements. * Induction hardened and ground raceways (sizes 28-42) * Nitrided, black oxidized and polished raceways (size 18) * Adjustable preload.
