The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SLS-C1-N-0 (R201221404) is a high-precision ball runner block designed for linear motion applications where space is restricted in the transverse direction. This component is part of the Ball Rail Systems product group and is particularly suitable for use with SNS ball guide rails. It boasts a slimline width, long length, and standard height format (SLS), ensuring a compact design while providing maximum precision. Constructed from corrosion-resistant steel in accordance with DIN standards, this runner block body and all its steel components are engineered to withstand harsh environments, making it ideal for applications involving water-based media, acidic materials, alkali or saline solutions, as well as high relative humidity and temperatures. Its resistance to corrosion also makes it suitable for clean rooms and electronics manufacturing processes. The B.RUNN. BLOCK NRII features a low preload class C and standard accuracy class N without a ball chain or initial lubrication, allowing for straightforward integration into existing systems. The optimized entry zone geometry combined with a high number of balls ensures minimal variation in elastic deflection and reduced frictional oscillations under load. This model can accommodate attachments mounted from above the block and allows for long-term lubrication over several years due to its minimum quantity lubrication system with an integrated reservoir. It offers excellent dynamic load capacities and load moments based on DIN ISO standards, maintaining high performance even under varied loading directions thanks to its four-row ball configuration. With an overall length of 70 mm and compatibility across various sizes of profiled rail systems (including sizes A, B, E, H, K, N, S), the Bosch Rexroth ball runner block provides versatility and reliability for diverse linear motion requirements. Its design facilitates self-alignment to compensate for misalignments without compromising movement efficiency or load capacity.
