The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-H-1 (R16518132Z) is a high-precision ball runner block designed for linear motion systems. This runner block is part of the Ball Rail Systems product line and adheres to DIN standards for linear guides, ensuring compatibility and reliability. The B.RUNNER BLOCK CS features a size FNS format, which includes a width flange, normal length, and standard height. It is constructed from unalloyed steel CS for durability. The runner block boasts a low preload class C and high accuracy class H, making it suitable for applications requiring maximum precision and rigidity. It does not include a ball chain but comes with initial lubrication and preservation using Roller bearing grease Dynalub. Designed without attachment elements on both the left and right front reference edges, it allows for flexibility in mounting. This model has an overall length of . mm and can be interchangeably used with guide rails of every accuracy level. It excels in applications that demand high rigidity, excellent dynamic characteristics, reduced frictional oscillations, and low friction force levels, especially under external loads. Additional features include straight lube connections that are loosely attached, integrated all-around sealing to protect against contaminants, and high torque load capacity. The runner block can be preloaded in an O-arrangement for maximum system rigidity. For enhanced functionality, an optional integrated inductive measuring system is available. The B.RUNNER BLOCK CS is pre-lubricated at the factory to support long-term lubrication over several years while maintaining high load ratings in all four main loading directions. Its design also includes two additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. This product is compatible with all SN/SNO ball guide rails offered by Bosch Rexroth and supports various preload classes to meet different application requirements. The dynamic load capacity C and static longitudinal moment load capacity ML are determined based on a 100 km travel as per DIN ISO standards. The permissible ambient temperature range for operation extends from min ... max °C; however, consultation is advised for use at negative temperatures.
