The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SNS-C1-H-0 (R201121304) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high accuracy. This product features a size 25 runner block body made of Resist NRII, a corrosion-resistant steel that conforms to DIN EN standards, ensuring durability in harsh environments. The SNS format implies a slimline width, normal length, and standard height configuration. The runner block operates with low preload (class C) and offers high accuracy (class H), making it suitable for applications where precision movement is critical. It lacks a ball chain and does not come with initial lubrication or preservation, allowing users to customize the lubrication system according to their specific requirements. One of the standout capabilities of this model is its ability to be used on all SNS ball guide rails available in five common sizes, providing versatility in application. It also has lube fittings with metal threads on all sides for easy maintenance and a minimum quantity lubrication system integrated into the design for long-term oil lubrication. The optimized entry-zone geometry coupled with a high number of balls minimizes variation in elastic deflection, which contributes to the unit's excellent dynamic characteristics. The integrated all-around sealing helps protect against contaminants, extending the service life even under challenging conditions. With an overall length of 63 mm and an impressive dynamic load capacity (C), this runner block can handle significant loads from all four main directions. The low friction coefficient ensures smooth operation while reducing heat generation during use. Furthermore, it boasts self-aligning capabilities for compensation of misalignments without self-alignment. This Bosch Rexroth ball runner block is designed for use where space is limited in the transverse direction and where long-term reliable operation is essential. Its robust construction makes it ideal for various industrial applications requiring both precision and resilience against corrosive elements.
