The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-FLS-C0-H-0 (R200229304) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This model features a Resist NRII construction, ensuring durability and longevity even in harsh environments. The block has a size designation of 025 and is part of the FLS format, which indicates a flange width, long length, and standard height. It boasts an accuracy class H for high precision and comes preload-free (preload class C), allowing for smooth motion without initial tension. The runner block body, along with all steel components, is made from corrosion-resistant steel compliant with DIN standards. Notably, this model does not include a ball chain or any preservation measures and comes without initial lubrication or attachment elements on the left or right front reference edges. The straight lube connection is loosely attached for ease of maintenance. With an overall length of the runner block at . mm, it offers interchangeability with guide rails across different accuracy classes. Its design caters to demanding rigidity requirements and supports long-term lubrication over several years while maintaining maximum precision. The patented entry zone significantly enhances travel accuracy by up to six times. This Bosch Rexroth runner block can be utilized on all SNS ball guide rails and is available in five common sizes. It features lube fittings with metal threads on all sides and delivers high load ratings in four main loading directions due to its robust design. The dynamic characteristics are exceptional, supported by an optimized entry-zone geometry that reduces variation in elastic deflection. The product's height is . mm when paired with Size E profiled rail systems. It operates within a permissible ambient temperature range of min ... max °C but consults are recommended for use at negative temperatures. Furthermore, it has impressive dynamic load capacity C and torsional moment load capacities Mt based on DIN ISO standards for travel lengths up to . m. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-FLS-C0-H-0 (R200229304) offers exceptional performance for applications that demand high precision, corrosion resistance, and dynamic capabilities without requiring immediate lubrication or additional sealing measures upon installation.
