The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SLS-C1-P-0 (R201281204) is a ball runner block designed for precision and corrosion resistance, suitable for applications with limited space in the transverse direction. This runner block is made from Resist NRII, a corrosion-resistant steel compliant with DIN EN standards, ensuring durability in harsh environments. With its SLS format (slimline width, long length, standard height), it offers a compact design without compromising on performance. The B.RUNN. BLOCK NRII features a low preload class C and an accuracy class P, indicating its precision manufacturing for high-accuracy requirements. It does not include a ball chain, initial lubrication, preservation, or attachment elements on either reference edge. The straight lube connection is loosely attached for convenience. This product boasts an overall length of 70 mm and can be interchanged with guide rails of every accuracy level to provide flexibility in system design. Its patented entry zone increases travel accuracy up to six times while reducing frictional oscillations and maintaining a low friction force level under external loads. The ball runner block 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. Designed to withstand ambient temperatures ranging from -10°C to +100°C (with short-term tolerance), the B.RUNN. BLOCK NRII also has impressive load ratings in all four main loading directions due to its robust construction. Attachments can be mounted from above the runner block height of 23 mm. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SLS-C1-P-0 provides maximum precision and corrosion resistance for linear motion applications where space is at a premium and reliability is paramount.
