The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C0-H-0 (R201189304) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications where space is limited in the transverse direction. This model features a slimline width, normal length, and standard height (SNS format) with an overall length of the runner block at 20 mm. The body and all steel components are made from corrosion-resistant steel according to DIN standards. This ball runner block is preload-free (preload class C) and offers high accuracy (accuracy class H), ensuring precise movements without the need for initial lubrication or preservation. It does not include a ball chain, attachment elements, or a straight lube connection which is loosely attached. It's designed to be interchangeable with guide rails of every accuracy level. The B.RUNN. BLOCK NRII has an impressive dynamic load capacity and static load rating, supporting high loads in all four main directions of loading. The entry zone has been optimized to increase travel accuracy up to six times and reduce frictional oscillations under external load conditions. Furthermore, the model comes with an integrated minimum quantity lubrication system that allows for long-term lubrication over several years. The sealing system is comprehensive and designed for all-round protection against contaminants which could potentially reduce its service life. This Bosch Rexroth runner block can operate within an ambient temperature range of -10°C to +100°C for short periods and features low-friction seals as standard with options for increased exposure protection available as accessories. In summary, the B.RUNN. BLOCK NRII KWD-020-SNS-C0-H-0 is ideal for applications requiring precise linear movement in corrosive environments or where space constraints exist. Its robust design ensures longevity and consistent performance even under demanding conditions.
