  • Bosh Rexroth R162171320 Ball Runner Block SNH, Size 30, C1, Accuracy class H, SS, Pre-lubricated BSHP Ball Runner Block SNH, Slimline, normal, high, standard, steel, without ball chain, R1621 … 2. Area of application: For restricted space in transverse direction and high rigidity requirements Higher rigidity than SNS Significantly reduced frictional oscillations and low friction level, particularly under external load Maximum precision Patented entry zone increases the travel accuracy up to a factor of six High rigidity in all load directions – permits applications with just one runner block per rail High torque capacity Limitless interchangeability as all Ball Rail Systems can be combined at will with all Ball Runner Block versions within each accuracy class. Long-term lubrication is possible over several years End-face fastening thread for all attachments Smooth, quiet running thanks to optimally designed ball return and guidance Different preload classes Excellent dynamic characteristics Can be used on all SNS/SNO Ball Guide Rails Ball Runner Block pre-lubricated at the factory 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
