The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C1-H-0 (R201181304) is a ball runner block designed for precision and corrosion resistance, suitable for use in environments where space is limited in the transverse direction. This model features a slimline width, standard height, and normal length format (SNS), with the body and all steel components constructed from corrosion-resistant steel conforming to DIN standards. The runner block offers low preload (class C) and high accuracy (class H), without a ball chain. The product's overall length is 20 mm, and it can be interchangeably combined with SNS ball guide rails of every accuracy level. Its design ensures long-term lubrication over several years, significantly reduced frictional oscillations, and a low friction force level even under external load. The patented entry zone of the runner block increases travel accuracy by up to six times. It has excellent dynamic characteristics due to its optimized entry zone geometry and high number of balls which minimize variation in elastic deflection. The runner block also features an integrated all-around sealing system and can withstand ambient temperatures ranging from minimum to maximum degrees Celsius for short durations—consultation is recommended for operation at negative temperatures. The dynamic load capacity C of this model is determined based on a 100,000 m travel as per DIN ISO norms. For applications requiring less travel, corresponding values can be calculated by adjusting the given values accordingly. This model comes without initial lubrication or preservation and allows attachments to be mounted from above. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C1-H-0 (R201181304) offers high precision, durability against corrosion, long-term lubrication capabilities, and versatile application potential due to its compatibility with various SNS ball guide rails sizes and its robust design that maintains high performance under diverse operating conditions.
