The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-FNS-C1-P-0 (R200121204) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This runner block is part of the Ball Rail Systems and features the Resist NRII material, which provides excellent resistance to corrosive substances such as water-based media, diluted acids, alkalis, and saline solutions. It has an FNS format indicating a flanged width, normal length, and standard height. The B.RUNN. BLOCK NRII KWD-025-FNS-C1-P-0 boasts a preload class C (low preload) and an accuracy class P (precision), ensuring smooth movement with minimal play for precise positioning tasks. The steel components, including the body of the runner block, are made according to DIN EN standards for corrosion-resistant steel, making it suitable for cleanroom environments or printed circuit board manufacturing where high humidity and temperature conditions prevail. This model does not come with a ball chain, initial lubrication, or preservation; it also lacks attachment elements on both front reference edges. It features straight lube connections that are loosely attached for ease of maintenance. The optimized entry-zone geometry combined with a high number of balls ensures reduced variation in elastic deflection under load. With its size E profiled rail system compatibility, this runner block can handle dynamic load capacities effectively while maintaining excellent dynamic characteristics in all four main loading directions. It is equipped with lube fittings on all sides for long-term lubrication possibilities over several years without frequent maintenance requirements. Additionally, this Bosch Rexroth ball runner block offers interchangeability with guide rails across all accuracy classes to meet various rigidity requirements without compromising travel accuracy or load capacity. The product is well-suited for applications that demand maximum precision and durability in challenging environments.
