The Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-SLS-C1-H-0 (R201211304) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications where space is limited in the transverse direction. This model is part of the Ball Rail Systems product group and is made from Resist NRII, a material that withstands harsh environments including water-based media, acidic materials, alkali or saline solutions, and high humidity above 100% with temperatures exceeding 100°C. With an accuracy class H for high precision and a preload class C indicating low preload, this runner block ensures smooth movement without excessive preloading. It features a slimline width (SLS format), long length, and standard height without a ball chain or initial lubrication. The absence of preservation makes it suitable for clean room applications and general printed circuit board manufacturing. The runner block body is standard with an overall length of 70 mm and can be used interchangeably with guide rails of every accuracy level. It supports dynamic load capacities based on DIN ISO standards and offers high load ratings in all four main loading directions. Long-term lubrication options are available for several years of operation without maintenance, thanks to its minimum quantity lubrication system with an integrated oil reservoir. This Bosch Rexroth model boasts optimized entry-zone geometry to reduce variation in elastic deflection significantly and has multiple lube fittings with metal threads. Attachments can be mounted from above on the runner block for ease of assembly. The permissible ambient temperature range for this unit spans from -10°C to +100°C (short term), ensuring reliable performance across various operating conditions. In summary, the B.RUNN. BLOCK NRII KWD-015-SLS-C1-H-0 offers exceptional durability and precision for applications requiring robust linear guidance under challenging environmental conditions or in space-restricted installations.
