The Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-FNS-C0-N-0 (R200139404) is a ball runner block designed for high rigidity applications, offering maximum precision and long-term lubrication capabilities over several years. This model features a Resist NRII body, which is corrosion-resistant and made of steel in accordance with DIN EN standards. It ensures excellent dynamic characteristics due to its optimized entry zone geometry, which increases travel accuracy up to six times. The runner block is preload-free (preload class C), has standard accuracy (class N), and does not include a ball chain, initial lubrication, preservation, or attachment elements at the left or right front reference edges. The straight lube connection is loosely attached. It can be used on all SNS ball guide rails and is available in five common sizes. The product also boasts metal-threaded lube fittings on all sides, maintaining high load ratings in all four main loading directions. Dynamic characteristics are enhanced due to the minimum quantity lubrication system with an integrated reservoir for oil lubrication. The overall length of the runner block is specified, and it can handle a maximum acceleration and permissible linear speed within defined parameters. Seals such as the standard seal SS are used to prevent contaminants from entering the ball runner block, extending its service life. For different environmental requirements, low-friction seal LS, double-lip seal DS, front seal options, FKM seal for extreme conditions, and cover plate wiper for coarse dirt environments are available as accessories. This Bosch Rexroth linear guide system is particularly suitable for environments where corrosion resistance and clean operation are essential such as clean rooms or manufacturing processes exposed to water-based media or high humidity conditions.
