The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-S-1 (R16518312Y) is a highly precise ball runner block designed for linear motion applications requiring high rigidity and maximum precision. This runner block is part of the Ball Rail Systems product group, which offers a robust solution for guiding and transporting loads with reduced frictional oscillations and low friction force levels, particularly under external load conditions. With an overall length of . mm, the B.RUNNER BLOCK CS features a flanged width (FNS format), normal length, and standard height. It is constructed from unalloyed steel CS for durability and comes with a high preload class C, indicating it is preloaded to achieve higher rigidity. This model boasts super precision (accuracy class SP) due to its optimized entry zone geometry, which increases travel accuracy by up to six times compared to conventional systems. The B.RUNNER BLOCK CS is equipped with a ball chain that ensures low noise levels and optimal travel behavior. It includes initial lubrication and preservation for maintenance-free operation over several years. The runner block body has straight lube connections loosely attached for easy access to lubrication points. This ball runner block can be used on all SN/SNO ball guide rails and supports high load ratings in all four main loading directions due to its design with four rows of balls providing point contact. The product also features integrated all-around sealing to protect against contaminants, ensuring long service life. Additional features include high torque load capacity, different preload classes for application-specific requirements, two additional mounting screw holes at the center for improved rigidity under lift-off and side loading conditions, and an optional integrated inductive measuring system for wear-free position detection. This model's versatility allows it to be used in various applications where precise movement is critical. Its design permits the use of just one runner block per rail if necessary while maintaining system rigidity through a preloaded O-arrangement.
