The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C2-P-0 (R200182204) is a high-performance ball runner block designed for precision linear motion applications. This runner block is made from Resist NRII, a corrosion-resistant steel that meets DIN EN standards, making it suitable for environments with water-based media, acidic materials, alkali, saline solutions, and high humidity or temperatures. It is particularly well-suited for clean room applications and printed circuit board manufacturing due to its lack of additional corrosion protection requirements. The B.RUNN. BLOCK NRII features a size 20 profile with a medium preload class C and an accuracy class P for precision motion control. It does not come with a ball chain, initial lubrication, or preservation, allowing for customization based on the specific application needs. The runner block has an overall length of 90 mm and offers high rigidity and long-term lubrication capabilities over several years. This ball runner block can be used with all SNS ball guide rails and is available in five common sizes to accommodate various design requirements. It includes lube fittings with metal threads on all sides to ensure easy maintenance and reliable performance. The patented entry zone of the runner block enhances travel accuracy significantly. Dynamic characteristics are exceptional due to the optimized entry-zone geometry and a high number of balls which minimize variation in elastic deflection. The unit can handle maximum load ratings in all four main loading directions due to its robust design. For sealing options, standard SS seals are provided for effective protection against contaminants such as dirt or chips. Additional sealing options like low-friction LS seals or double-lip DS seals are available for more demanding environments. Overall, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C2-P-0 offers excellent dynamic properties and versatility for various industrial applications where precision linear movement is critical under challenging conditions.
