The Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-SLS-C1-N-0 (R201231404) is a high-precision ball runner block designed for linear motion systems that require corrosion resistance and precision. This model is part of the SLS series, which stands for slimline width, long length, and standard height, ensuring that it fits perfectly in applications with limited transverse space. The runner block body and all steel components are crafted from corrosion-resistant steel according to DIN standards, which provides durability and longevity. This particular ball runner block features a low preload class C and a standard accuracy class N. It does not include a ball chain, preservation or initial lubrication, enabling users to customize their lubrication strategy according to their specific application needs. The overall length of the runner block is 70 mm, making it compact yet robust for various uses. The B.RUNN. BLOCK NRII is designed to be interchangeable with guide rails of every accuracy level within the product range. Its patented entry zone significantly increases travel accuracy by up to six times while reducing frictional oscillations and maintaining a low friction force level even under external loads. Suitable for all SNS ball guide rails, this model offers flexible installation options with lube fittings featuring metal threads on all sides. It provides high load ratings in all four main directions of loading and supports long-term lubrication over several years through its minimum quantity lubrication system with an integrated oil reservoir. The optimized geometry ensures minimal variation in elastic deflection during operation. Attachments can be easily mounted from above due to the design of the runner block's top surface. With its dynamic load capacity C determined as per DIN ISO 14728 standards, this Bosch Rexroth ball runner block is engineered for reliability and performance in demanding linear motion tasks.
