The Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-SNS-C1-P-0 (R201131204) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This runner block is part of the Ball Rail Systems series and is made from Resist NRII, a corrosion-resistant steel that conforms to DIN EN standards, making it suitable for environments with water-based media, diluted acids, alkalis, saline solutions, or high humidity. The block features a size SNS format which denotes its slim width, normal length, and standard height dimensions. The body of the runner block and all steel components are made of corrosion-resistant steel. It comes with a low preload class C and an accuracy class P for precision applications. Notably, this model does not include a ball chain, preservation measures, initial lubrication or attachment elements on either front reference edge. With an overall length of 70 mm and capable of being used on all SNS ball guide rails, the B.RUNN. BLOCK NRII offers interchangeability across various accuracy classes. It can sustain long-term lubrication over several years without degradation in performance due to its minimum quantity lubrication system with integrated reservoirs for oil lubrication. This model boasts reduced frictional oscillations and low friction levels under external load due to its patented entry zone that improves travel accuracy significantly—up to six times better than standard blocks. Additionally, it maintains high load ratings in all four main directions of loading. The optimized entry zone geometry combined with a high number of balls reduces variation in elastic deflection while providing excellent dynamic characteristics. The integrated all-around sealing ensures that contaminants are kept out effectively without compromising movement ease. This Bosch Rexroth ball runner block is ideal for applications where space is limited in the transverse direction but where precision and durability are critical—such as in clean rooms or circuit board manufacturing environments where contamination control is paramount.
