The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C1-N-1 (R16538142Y) is a high precision ball runner block designed for linear motion applications where rigidity, low friction, and longevity are crucial. This runner block is characterized by its FLS size format, which denotes a width flange, long length, and standard height. Constructed from unalloyed steel CS, it features a low preload class C and a standard accuracy class N. The inclusion of a ball chain facilitates smooth movement and reduced noise levels. This runner block is prelubricated with Roller bearing grease Dynalub for immediate use and offers long-term lubrication possibilities spanning several years. It does not come with attachment elements at the front reference edges but has straight lube connections loosely attached. The overall length of the runner block allows for interchangeability with guide rails of every accuracy level. It's engineered to meet demanding rigidity requirements with significantly reduced frictional oscillations and low friction force levels, especially under external loads. Its dynamic characteristics are enhanced by a patented entry zone that can increase travel accuracy by up to six times. The design also includes integrated all-around sealing and high torque load capacity while allowing for different preload classes. The B.RUNNER BLOCK CS can be used in applications requiring just one runner block per rail due to its high rigidity in all load directions. It offers improved rigidity under lift-off and side loading conditions thanks to additional mounting screw holes at the center of the block. For maximum system rigidity, it features a preloaded O-arrangement. An optional integrated inductive measuring system adds to its versatility without wear concerns. Attachments can be mounted from both above and below on the runner block body which comes in a standard version. It is compatible with all SN/SNO ball guide rails while maintaining high load ratings in all four main directions of loading.
