The Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-FLS-C1-P-0 (R200211206) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This runner block features a Resist NRII body, which is made from corrosion-resistant steel in accordance with DIN EN standards, making it suitable for use in harsh environments such as those with water-based media, acidic materials, alkali or saline solutions, and high humidity or temperature conditions. It is also ideal for clean room applications and general printed circuit board manufacturing. The B.RUNN. BLOCK NRII KWD-015-FLS-C1-P-0 has a size of 15 and comes in the FLS format, which denotes a flanged width, long length, and standard height. The preload class C indicates a low preload while the accuracy class P stands for precision grade. The presence of a ball chain contributes to the unit's low noise level and smooth travel behavior. This model does not come with initial lubrication or preservation, allowing users to apply their choice of lubricants based on specific application needs. The straight lube connection is loosely attached for ease of maintenance. The runner block’s overall length is . mm, ensuring compatibility with various guide rail sizes. The dynamic characteristics of this ball runner block are enhanced by its optimized entry zone geometry and the high number of balls it houses. These features work together to minimize variation in elastic deflection under load. Additionally, it offers excellent dynamic load capacity (C), static load rating (C0), dynamic torsional moment load capacity (Mt), and static longitudinal moment load capacity (ML), providing reliable performance even under demanding rigidity requirements. Designed to be interchangeable with guide rails across different accuracy classes without sacrificing travel accuracy or load-bearing capabilities, this Bosch Rexroth ball runner block system can sustain high load ratings in all four main directions of loading. Its minimum quantity lubrication system includes an integrated reservoir for oil lubrication that allows long-term maintenance-free operation over several years.
