The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C1-H-0 (R200181304) is a high-precision ball runner block designed for linear motion applications where corrosion resistance, rigidity, and accuracy are paramount. This product is part of the Ball Rail Systems and is made from Resist NRII, a corrosion-resistant steel that conforms to DIN EN standards, making it suitable for use in harsh environments such as electroplating and pickling lines, or clean rooms. The B.RUNN. BLOCK NRII features a size 20 runner block with an FNS format, indicating a flange width, normal length, and standard height. It has a low preload class C and a high accuracy class H but does not include a ball chain. The runner block body is in the standard version without initial lubrication or preservation. This model's optimized entry zone geometry allows for increased travel accuracy by up to six times compared to conventional designs. It can be used with all SNS Ball Guide Rails and offers excellent dynamic characteristics due to its design that accommodates four rows of balls with point contact in all loading directions. The Bosch Rexroth ball runner block has an overall length of 0 mm and boasts high load ratings in all four main loading directions. It also features lube fittings with metal threads on all sides for easy maintenance. The product's design ensures minimum variation in elastic deflection due to its high number of balls and optimized entry zone geometry. Sealing options include the standard seal SS for universal applications, low-friction seal LS for ease of movement requirements, double-lip seal DS for increased exposure to media, front seals for environments with fine dirt or metal particles, FKM seals for extreme conditions, and cover plate wipers for coarse dirt or chips environments. The B.RUNN. BLOCK NRII KWD-020-FNS-C1-H-0 offers long-term lubrication potential over several years and supports maximum precision in linear motion tasks across various applications where durability and precision are critical factors.
