The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FLS-C1-H-1 (R165321323) is a high-precision ball runner block designed for linear motion and guidance applications. It features a size 25 flanged long standard (FLS) format, with a runner block body made of unalloyed steel CS, ensuring durability and robust performance. The product is characterized by its low preload class C and high accuracy class H, providing smooth motion with minimal play and exceptional precision. Equipped with an innovative ball chain, this runner block facilitates quiet operation and optimal travel behavior. The inclusion of initial lubrication and preservation means the block is ready for use upon delivery, while the roller bearing grease Dynalub offers long-term lubrication capabilities that can extend over several years. This model also boasts a straight lube connection that is loosely attached for ease of maintenance. For applications requiring maximum rigidity, this ball runner block is designed to withstand demanding requirements, including significantly reduced frictional oscillations and low friction levels under external loads. Its excellent dynamic characteristics are enhanced by the patented entry zone which increases travel accuracy substantially. The B.RUNNER BLOCK CS KWD-025-FLS-C1-H-1 comes without attachment elements at the front reference edges but features end-face fastening threads for various attachments. Its all-around sealing ensures protection against contaminants, contributing to its high torque load capacity. Various preload classes are available to suit different application needs. This ball runner block is interchangeable with guide rails of every accuracy, offering flexibility in system design. It's also suitable for use on all SN/SNO ball guide rails provided by Bosch Rexroth, maintaining the same high load ratings in all four main loading directions. The additional mounting screw holes at the center enhance rigidity under liftoff and side loading conditions, ensuring maximum system rigidity when used in preloaded O-arrangement configurations. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FLS-C1-H-1 (R165321323) represents a versatile and reliable solution for sophisticated linear motion tasks where precision and longevity are paramount.
