The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SLS-C2-H-0 (R201222304) is a highly precise, corrosion-resistant ball runner block designed for applications with limited space in the transverse direction. This model features a size 25 Resist NRII runner block body, with all steel components manufactured from corrosion-resistant steel according to DIN standards. It offers medium preload (class C) and high accuracy (class H), ensuring reliable performance and longevity. The runner block is part of the SLS format, characterized by its slim width, long length, and standard height. It does not come with a ball chain, preservation, initial lubrication, or attachment elements for the left or right front reference edges. The product also includes a straight lube connection that is loosely attached. This model boasts an overall length of 70 mm and is compatible with all SNS ball guide rails, allowing interchangeability across various accuracy levels. Its patented entry zone increases travel accuracy by up to six times while significantly reducing frictional oscillations and maintaining a low friction force level under external loads. The B.RUNN. BLOCK NRII KWD-025-SLS-C2-H-0 supports long-term lubrication over several years through its minimum quantity lubrication system with an integrated oil reservoir. The optimized entry-zone geometry coupled with a high number of balls reduces variation in elastic deflection. Attachments to the ball runner block can be mounted from above, providing ease of use and flexibility in installation. The unit can handle dynamic load capacities effectively as per DIN ISO standards and offers excellent load ratings in all four main loading directions. In summary, this Bosch Rexroth ball runner block is engineered for maximum precision and durability in harsh environments where corrosion resistance and space constraints are significant factors. It's an ideal component for sophisticated linear motion applications requiring robust performance and minimal maintenance.
