The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SNS-C0-H-0 (R201129304) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications where space is limited in the transverse direction. This runner block boasts an SNS size format, indicating its slimline width, normal length, and standard height. The body and all steel components are crafted from corrosion-resistant steel according to DIN standards. The product features a preload class C, meaning it is preload-free, and an accuracy class H for high precision. It comes without a ball chain, preservation, initial lubrication, or attachment elements on either the left or right front reference edge. The runner block also includes a straight lube connection that is loosely attached. With an overall length of 70 mm, this ball runner block is interchangeable with guide rails of every accuracy level. It is designed for long-term lubrication over several years and can withstand significant reduced frictional oscillations and low friction force levels under external load. The patented entry zone increases travel accuracy by up to six times. This model can be used with all SNS ball guide rails and supports attachments mounted from above. It features a minimum quantity lubrication system with an integrated reservoir for oil lubrication and optimized entry-zone geometry with a high number of balls to minimize variation in elastic deflection. Dynamic characteristics are enhanced by the product's design, which includes integrated all-around sealing. The permissible ambient temperature range for this runner block spans from -10°C to +100°C (admissible for short periods), ensuring its functionality across various environments. The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SNS-C0-H-0 has dynamic load capacity C based on a 100 km travel as per DIN ISO standards and offers excellent dynamic characteristics due to its design which reduces friction coefficients between 0.01 to 0.02 without the seal's friction included. This product's robust construction makes it suitable for diverse applications including clean rooms and circuit board manufacturing due to its corrosion resistance against water-based media, acidic materials, alkali solutions, saline solutions as well as in environments with high humidity or temperatures above 100°C.
