  • Bosh Rexroth R166211420 Super Ball Runner Block SKS, Size 15, C1 Moderate preload, Accuracy class N, SS Standard seal, Pre-lubricated Super Ball Runner Block SKS, steel, self-aligning, R1662 … 2. Area of application: For compensating higher tolerances with connected structures Low noise level and outstanding travel behavior Excellent dynamic characteristics Limitless interchangeability as all Ball Rail Systems can be combined at will with all Ball Runner Block versions within each accuracy class. Extra-compact design Compensates own misalignments (for deviations up to 10' in 2 levels) The same high load ratings in all four main directions of loading Lube fittings with metal threads on all sides Smooth operation due to optimal return and ball pick-up and entry design Preload classes: C0 (without preload, clearance) and C1 (moderate preload) Enables greater parallelism and height offsets of mounting bases Can be used on all SNS Ball Guide Rails Due to the Rexroth design with four rows of balls, 2-point contact is available in all loading directions. This reduces the friction to a minimum. Other ball rail systems with two or four rows of balls with 4-point contact have multiple friction: due to the differential slip with lateral loading and in case of comparable prestressing without the load, the gothic raceway profile causes higher friction (depending on the raceway curvature and the load, up to five times the friction coefficient). This high friction leads correspondingly to greater heat. Seals Seals are use to prevent dirt, chips and coolants, etc. from working their way into the inside of he Ball Runner Block, thereby preventing reductions to its service life. Standard seal (SS) Universal seals are fitted as standard in Rexroth Ball Runner Blocks. They have a uniform sealing effect for Ball Guide Rails with and without cover strips. Low friction and a good sealing effect have both been taken into account in the design. For applications where effective sealing is required. Low-friction seal (LS) For special requirements with regard to ease of movement. Double-lip seal (DS) For increased exposure to media Front seal For applications in environments with fine dirt or metal particles, as well as coolants or cutting fluids. Interchangeable during servicing. FKM seal For applications in extreme environments with fine dirt or metal particles, as well as heavy use of coolants or cutting fluids. Interchangeable during servicing. Cover plate wiper For use in environments with coarse dirt or chips Preload classes C0 = Without preload (clearance) C1 = Moderate preload C2 = Average preload C3 = High preload
