The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C3-S-1 (R165133122) is a highly precise ball runner block designed for linear motion systems requiring high rigidity and precision. This model features a size FNS format, which includes a width flange, normal length, and standard height. The runner block body is constructed from unalloyed steel CS, ensuring durability and robustness in demanding applications. This particular model comes with a high preload class C and an accuracy class of SP for super precision. It is equipped with a ball chain that contributes to low noise levels and optimal travel behavior. The initial lubrication and preservation are handled at the factory, which simplifies maintenance for the user. One of the key capabilities of this runner block is its ability to offer significantly reduced frictional oscillations and maintain a low friction force level, especially under external loads. This is enhanced by its patented entry zone, which can increase travel accuracy by up to six times. The design also allows attachments to be mounted from both above and below the runner block. The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C3-S-1 features integrated all-around sealing for protection against contaminants and offers high torque load capacity due to its optimized design. It boasts different preload classes to cater to varying application requirements and comes with optimized entry-zone geometry paired with a high number of balls to minimize variation in elastic deflection. This model supports applications that require just one runner block per rail due to its high rigidity in all load directions. Additionally, it has improved rigidity under lift-off and side-loading conditions because of two extra mounting screw holes at the center of the runner block. The B.RUNNER BLOCK CS KWD-035-FNS-C3-S-1 can be used on all SNS/SNO ball guide rails offered by Bosch Rexroth. It has identical high load ratings in all four main directions of loading, making it versatile for various linear motion setups. Long-term lubrication capabilities extend over several years, reducing maintenance frequency.
