The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C1-N-0 (R201181404) is a high-quality ball runner block designed for precision linear motion applications. This product features a slimline width, normal length, and standard height in the SNS format, with the runner block body and all steel components constructed from corrosion-resistant steel per DIN standards. It boasts a low preload class C and standard accuracy class N, ensuring smooth operation with minimal friction. This runner block is notable for its absence of a ball chain, preservation, initial lubrication, and attachment elements on both front reference edges. The straight lube connection is loosely attached for ease of maintenance. With an overall length of 63 mm, this runner block provides interchangeability across various guide rails with different accuracy levels. Designed for use in restricted spaces where transverse direction space is limited, this model offers long-term lubrication capabilities spanning several years. Its construction from corrosion-resistant materials ensures durability even in harsh environments. The patented entry zone amplifies travel accuracy significantly—up to six times—making it suitable for applications that demand high precision. The B.RUNN. BLOCK NRII KWD-020-SNS-C1-N-0 can accommodate attachments mounted from above and features an integrated minimum quantity lubrication system with an oil reservoir. Its optimized entry-zone geometry and substantial number of balls reduce elastic deflection variation while providing excellent dynamic characteristics. This runner block operates efficiently within a permissible ambient temperature range of -10°C to +100°C (admissible for short periods), though consultation is recommended for use at negative temperatures. It supports maximum accelerations up to 50 m/s² (when specific force conditions are met) and has a nominal size of 20. Overall, the Bosch Rexroth ball runner block is engineered to deliver superior performance with its advanced design features such as all-around sealing for protection against contaminants and the capability to withstand high load ratings in all main loading directions.
