The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-P-1 (R165181222) is a high-precision ball runner block designed for linear motion applications requiring rigidity, precision, and smooth operation. This runner block features a size 20 steel CS body with a flange width, normal length, and standard height format (FNS). It is classified under the low preload class C and the precision accuracy class P. The product includes a ball chain that ensures low noise levels and optimal travel behavior. Equipped with initial lubrication and preservation, this runner block utilizes roller bearing grease Dynalub for reduced maintenance needs. It has straightforward lube connections that are loosely attached for ease of maintenance. The body of the runner block comes in a standard version without attachment elements on either front reference edge. The B.RUNNER BLOCK CS KWD-020-FNS-C1-P-1 boasts an overall length of . mm and offers interchangeability with guide rails across all accuracy classes. It's engineered to meet high rigidity requirements, significantly reduce frictional oscillations, and maintain low friction force levels even under external load. The patented entry zone of the runner block enhances travel accuracy by up to six times. This model includes several design features such as attachments that can be mounted from both above and below, metal-threaded lube fittings on all sides, endface fastening threads for all attachments, integrated all-around sealing, high torque load capacity, different preload classes, optimized entry-zone geometry with a high number of balls to minimize variation in elastic deflection, and improved rigidity under various loading conditions due to additional mounting screw holes at its center. The B.RUNNER BLOCK CS KWD-020-FNS-C1-P-1 is prelubricated at the factory for immediate use upon delivery and is compatible with all SN/SNO ball guide rails by Bosch Rexroth. Its design allows for long-term lubrication over several years while maintaining high load ratings in all four main loading directions.
