The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-SNH-C0-H-1 (R162149320) is a high-precision ball runner block designed for linear motion applications requiring compactness, high rigidity, and accuracy. This runner block is part of the Ball Rail Systems product group and is notable for its slimline width, standard length, and heightened profile (SNH format), tailored to fit within restricted spaces while providing exceptional rigidity. The model is made from unalloyed steel CS and falls under the preload class C, meaning it is preload-free. It also boasts a high accuracy class H. The R162149320 runner block has been designed without a ball chain but comes with initial lubrication and preservation to ensure smooth operation upon installation. Its straight lube connection is loosely attached for ease of maintenance. With an overall length specific to its design, this runner block ensures interchangeability across guide rails within the same accuracy class. This product supports high torque load capacity and allows for applications that use just one runner block per rail due to its high rigidity in all load directions. The patented entry zone of the runner block significantly enhances travel accuracy by up to six times, particularly under external loads. The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-SNH-C0-H-1 is prelubricated at the factory, which along with its optimized ball return and guideway design contributes to its smooth and quiet running characteristics. It supports various sealing options like standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper – each catering to different environmental conditions. With excellent dynamic characteristics and the ability to withstand different preload classes, this ball runner block can be used on all SN/SNO Ball Guide Rails. It's suitable for long-term lubrication over several years and features an end-face fastening thread for attachment purposes. The R162149320 model accommodates a wide range of permissible ambient temperatures and has been engineered with precision in mind for diverse linear motion applications.
