The Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-SKS-C1-N-0 (R201031404) is a high-precision ball runner block designed for linear motion applications where space is limited and corrosion resistance is essential. The runner block body, along with all steel components, is constructed from corrosion-resistant steel in accordance with DIN EN standards, ensuring durability and longevity even in harsh environments. With an overall length of 35 mm, this model features a slimline width, short length, and standard height (SKS format), making it suitable for compact installations. This runner block boasts a low preload class C and standard accuracy class N, without the inclusion of a ball chain or initial lubrication, providing a straightforward solution for various applications. It has been engineered to provide significantly reduced frictional oscillations and low friction force levels, especially under external load conditions. The patented entry zone contributes to enhanced travel accuracy by up to six times compared to conventional designs. Designed to deliver maximum precision while accommodating misalignments through its self-aligning capabilities, the B.RUNN. BLOCK NRII does not include self-alignment features as part of its standard configuration. It offers excellent dynamic characteristics due to optimized entry-zone geometry and a high number of balls, which minimize variation in elastic deflection. The product is compatible with all SNS ball guide rails and can handle high load ratings in all four main directions of loading. Additionally, it supports long-term lubrication over several years and includes an integrated reservoir for oil lubrication as part of its minimum quantity lubrication system. Attachments can be mounted from above the runner block which has a height of 14 mm. The product operates within an ambient temperature range of -10°C to +100°C but can withstand higher temperatures for short periods; consultation is recommended for use at negative temperatures. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-SKS-C1-N-0 (R201031404) offers robust performance with its corrosion-resistant construction and precise movement capabilities suitable for space-restricted applications requiring long-term reliability and minimal maintenance.
