The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SKS-C1-N-0 (R201021404) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications requiring a compact and robust guide system. This product is part of the Ball Rail Systems and is characterized by its Resist NRII material, which offers exceptional durability in harsh environments, including exposure to water-based media, acidic materials, alkali or saline solutions, and high humidity levels above 80% or temperatures exceeding 100°C. The runner block features a slimline width format SKS with standard height and short length, providing an optimal solution for restricted spaces in both longitudinal and transverse directions. Its steel components are made according to DIN EN standards for corrosion resistance. The low preload class C ensures smooth movement with minimal frictional resistance, while the accuracy class N maintains standard precision levels. Notably, this model does not include a ball chain or initial lubrication and comes without attachment elements on either front reference edge. This runner block supports long-term lubrication over several years and can be combined with any SNS ball guide rails regardless of accuracy level due to its interchangeability feature. It boasts reduced frictional oscillations even under external loads and an enhanced travel accuracy thanks to its patented entry zone design. Furthermore, it offers excellent dynamic characteristics suitable for various applications where precise motion control is crucial. Additional specifications include a dynamic load capacity C based on DIN ISO standards for a 100 km travel distance (with a comparison factor for actual stipulated distances), permissible ambient temperature ranges from -10°C to +100°C (with consultation required for negative temperatures), and multiple lube fittings with metal threads for easy maintenance. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SKS-C1-N-0 (R201021404) presents an ideal choice for users seeking a reliable, corrosion-resistant linear guide system that provides maximum precision and durability in challenging environmental conditions.
