The Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-SNS-C2-P-0 (R201112206) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This robust component features a Resist NRII construction ensuring durability against corrosive environments. The block's dimensions adhere to the SNS format, indicating a slimline width, normal length, and standard height, which makes it suitable for applications with limited transverse space. The runner block boasts a medium preload (class C) and precision accuracy (class P), optimizing its performance in demanding situations. A distinctive feature of this model is the inclusion of a ball chain, which facilitates smooth movement and low noise operation while improving travel behavior. It does not come with initial lubrication or preservation, allowing users to apply their preferred lubrication solution according to specific application requirements. With an overall length of 70 mm, the B.RUNN. BLOCK NRII KWD-015-SNS-C2-P-0 can be used interchangeably with guide rails of every accuracy level within its class. The design incorporates an optimized entry zone geometry that significantly reduces frictional oscillations and provides low friction levels even under external loads. The patented entry zone also enhances travel accuracy by up to six times compared to standard entry zones. For long-term operation, this model supports several years of lubrication without the need for frequent maintenance. All metal parts are made from corrosion-resistant steel as per DIN standards, ensuring longevity and consistent performance in various industrial settings. Additional specifications include dynamic load capacity C based on 100 km travel as per DIN ISO standards, a permissible ambient temperature range from -10°C to +100°C for short periods, and self-aligning capabilities for compensation of misalignments. This runner block is ideal for use in profiled rail systems of sizes E, H, B, K, A, N, S, T with different tolerances specified in millimeters. It offers excellent dynamic characteristics across all four main loading directions and comes equipped with an integrated all-around sealing system for added protection against contaminants. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-SNS-C2-P-0 is a versatile and durable component suited for linear motion applications where precision and corrosion resistance are paramount. Its advanced features ensure reliable operation with minimal maintenance requirements across various industrial environments.
