The Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-SNS-C1-H-0 (R201131304) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and durability. This particular model is crafted from Resist NRII, a material known for its excellent corrosion-resistant properties, making it suitable for environments with water-based media, acidic materials, alkali solutions, or saline environments. The runner block's body and all steel components are made according to DIN EN standards to ensure robustness in harsh conditions. The B.RUNN. BLOCK NRII features a slimline width (SNS format), normal length, and standard height, which allows for versatility in restricted space applications. It boasts a low preload (class C) and high accuracy (class H), ensuring smooth motion and precise positioning without the aid of a ball chain. The absence of initial lubrication and preservation means that users can apply their choice of lubrication based on specific application needs. With an overall length of 70 mm and the capability to combine with guide rails of every accuracy level, this runner block offers flexibility in system design. Its dynamic load capacity is determined as per DIN ISO standards with the ability to handle high loads from all four main loading directions. The optimized entry zone geometry along with a high number of balls reduces elastic deflection variation, contributing to its excellent dynamic characteristics. Additionally, the B.RUNN. BLOCK NRII comes equipped with an integrated reservoir for oil lubrication that supports long-term maintenance-free operation over several years. Its sealing system provides protection against contaminants while maintaining low friction levels during movement. This Bosch Rexroth ball runner block is ideal for applications such as clean rooms, general printed circuit board manufacturing, or any setting where reduced frictional oscillations and low friction force levels are essential under external loads. It also offers easy mounting options from above for attachments on the block itself.
