The Bosch Rexroth B.RUNNER BLOCK NR KWD-030-SLS-C0-H-1 (R201279331) is a high-precision ball runner block designed for seamless motion and durability in various applications. This model boasts a slimline width, long length, and standard height, making it suitable for restricted spaces where transverse direction space is limited. The runner block body is constructed from corrosion-resistant steel according to DIN EN standards, ensuring longevity and resistance to harsh environments. With a preload class C, this runner block is preload-free, which helps to minimize friction and wear. It also falls into the high accuracy class H, making it ideal for applications requiring precise movements. The absence of a ball chain contributes to the unit's streamlined design and simplifies maintenance. The B.RUNNER BLOCK NR features an initial lubrication and preservation with Roller bearing grease Dynalub 510, which aids in achieving long-term lubrication over several years. Its dynamic characteristics are enhanced by its patented entry zone that can increase travel accuracy up to six times compared to conventional designs. This model has no attachment elements on the left or right front reference edges but includes a straight lube connection that is loosely attached. With an overall length of 70.4 mm and the ability to interchange with guide rails of every accuracy level, this ball runner block offers flexibility in use across various systems. It can withstand high torque loads and maintains the same high load ratings in all four primary loading directions. Notable capabilities include suitability for all SNS/SNO ball guide rails, fast delivery options recommended by Rexroth when corrosion protection is crucial, significantly reduced frictional oscillations even under external load conditions, and compatibility with attachments that can be mounted from above. The product's material profiled rail systems are made from corrosion-resistant steel with size N tolerance profiled rail systems measuring 15 mm in height. The permissible ambient temperature range for operation spans from -10°C up to +100°C (admissible for short periods). For dynamic load capacity C and other specific load ratings based on travel as per DIN ISO standards, users are advised to consult the detailed product specifications provided by Bosch Rexroth.
