The Bosch Rexroth B.RUNN. BLOCK NRII KWD-030-SNS-C2-P-0 (R201172204) is a state-of-the-art ball runner block designed for high precision and corrosion resistance in demanding applications. This product is part of the Ball Rail Systems and is characterized by its Resist NRII construction, making it suitable for use with water-based media, acidic materials, alkali or saline solutions, and in environments with high humidity or temperatures. The ball runner block features a size 30 slimline width (SNS format), standard height, and length, ensuring compatibility with restricted spaces in the transverse direction. Constructed from corrosion-resistant steel according to DIN EN standards, this runner block body includes all steel components made from the same durable material. It offers medium preload (class C) and precision accuracy (class P), catering to applications requiring precise motion control. Notably, this model does not come with a ball chain, initial lubrication, preservation, or attachment elements on either front reference edge. The Bosch Rexroth B.RUNN. BLOCK NRII can be used on all SNS ball guide rails and boasts interchangeable capabilities allowing it to be combined with guide rails of every accuracy level. It features an optimized entry zone geometry that significantly improves travel accuracy by reducing frictional oscillations and lowering the friction force level under external load. In terms of maintenance and operation efficiency, the product allows for long-term lubrication over several years without frequent re-lubrication needs due to its minimum quantity lubrication system with an integrated oil reservoir. It also comes equipped with lube fittings featuring metal threads on all sides for enhanced durability. The overall length of the runner block is 90 mm while maintaining high load ratings in all four main loading directions. Attachments can be mounted from above for ease of integration into various systems. The dynamic characteristics are excellent due to an optimized number of balls which minimizes variation in elastic deflection while ensuring reliable performance. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-030-SNS-C2-P-0 (R201172204) provides exceptional precision and corrosion resistance for linear motion applications where space is limited and environmental conditions are challenging.
