The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C1-P-0 (R201181204) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications where space is limited in the transverse direction and long-term lubrication is beneficial. This model features a slimline, normal, and standard height (SNS) format with an overall length of 20.5 mm and is made from Resist NRII material, ensuring durability and resistance to corrosive environments. The ball runner block boasts a low preload class C and precision accuracy class P, without a ball chain or initial lubrication, which facilitates reduced frictional oscillations and a low friction force level, especially under external load. Its patented entry zone significantly improves travel accuracy by up to six times compared to conventional designs. The block can be used with all SNS ball guide rails and supports a wide range of ambient temperatures from -10°C to +100°C. With its optimized entry-zone geometry and high number of balls, the B.RUNN. BLOCK NRII minimizes variation in elastic deflection, providing excellent dynamic characteristics suitable for various applications. It features integrated all-around sealing for protection against contaminants and allows for attachments to be mounted from above. This model has impressive load ratings in all four main directions of loading and includes lube fittings with metal threads on all sides for easy maintenance. The dynamic load capacity C is based on a 100 km travel as per DIN ISO 14728-1 standards, indicating robust performance over extended periods. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C1-P-0 (R201181204) offers exceptional precision and corrosion resistance for linear motion systems requiring long-term reliability in challenging environments. Its design ensures minimal frictional losses while maintaining high load capacities and dynamic performance across various industrial applications.
