The Bosch Rexroth B.RUNNER BLOCK CR KWC-065-FLS-C0-H-2 (R165369360) is a high-precision, corrosion-resistant ball runner block designed for demanding applications requiring maximum rigidity and load-bearing capacity. This runner block features a Resist CR coating for enhanced durability and resistance to corrosion. It is constructed with unalloyed steel CS, presenting a matte-silver, hard chrome-plated finish. The product is defined by its FLS size format, indicating a flanged width, long length, and standard height. The B.RUNNER BLOCK CR KWC-065-FLS-C0-H-2 is preload-free (Preload class C) and offers high accuracy (Accuracy class H). It does not include a ball chain or initial lubrication and comes without attachment elements at both left and right front reference edges. Angular lube nipples are provided but not attached. The overall length of the runner block is specified in the product details. This ball runner block is interchangeable with guide rails of every accuracy level, making it versatile for various installations. It's particularly suitable for heavy-duty machine construction due to its extremely high load-bearing capacity and rigidity in all load directions. The design includes two additional mounting screw holes at the center for improved stability under liftoff and side loading conditions. Furthermore, the optimized entry-zone geometry coupled with a high number of balls ensures minimal variation in elastic deflection while maintaining quiet and smooth operation. The factory pre-lubrication suggests that long-term lubrication over several years is possible without frequent maintenance. Additional features such as various sealing options including standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper cater to different environmental conditions by preventing contaminants from affecting the block's performance. These seals ensure that the ball runner block can operate effectively even in environments exposed to dirt, chips, coolants or cutting fluids.
