The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C1-H-0 (R201181306) is a high precision ball runner block designed for linear motion applications requiring corrosion resistance and high accuracy. This model is part of the SNS series, which stands for slimline width, normal length, and standard height, ensuring a compact design suitable for restricted spaces in the transverse direction. It boasts an overall length of 63 mm and offers a low preload class C and a high accuracy class H. The ball runner block is constructed from Resist NRII, a corrosion-resistant steel compliant with DIN EN standards. Featuring a ball chain mechanism, this runner block ensures low noise levels and smooth travel behavior. It's notable for its dynamic load capacity C and static longitudinal moment load capacity ML, which are based on a 100 km travel as per DIN ISO standards. The product has been engineered to provide significantly reduced frictional oscillations and maintain a low friction force level even under external loads. The B.RUNN. BLOCK NRII KWD-020-SNS-C1-H-0 does not come with initial lubrication or preservation but includes an integrated minimum quantity lubrication system with an oil reservoir to facilitate long-term maintenance-free operation over several years. Attachments can be mounted from above the block, which also features lube fittings with metal threads on all sides. This model is characterized by its optimized entry-zone geometry that increases travel accuracy substantially and has excellent dynamic characteristics due to the high number of balls that minimize variation in elastic deflection. The product also includes integrated all-around sealing to protect against contaminants while maintaining service life in harsh environments. Suitable for use in clean rooms and general printed circuit board manufacturing due to its lack of additional corrosion protection requirements, this ball runner block can be used across various SNS Ball Guide Rails sizes and maintains high load ratings in all four main loading directions.
