The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SNS-C1-H-0 (R201121306) is a high-precision, corrosion-resistant ball runner block designed for use with SNS profiled rail systems. This model features a Resist NRII material construction, ensuring durability and resistance to corrosive environments. The block is characterized by its slimline width, standard height, and normal length, conforming to the SNS format. It has a low preload class C and a high accuracy class H, indicating minimal pre-tension in the system for smooth movement and high positioning accuracy. The runner block body and all steel components are made of corrosion-resistant steel according to DIN standards. It comes equipped with a ball chain that contributes to low noise levels and optimal travel behavior. The absence of initial lubrication or preservation allows for customization according to specific application requirements. This model lacks attachment elements on the left and right front reference edges but includes a straight lube connection that is loosely attached. With an overall length of 52.4 mm, the B.RUNN. BLOCK NRII KWD-025-SNS-C1-H-0 offers interchangeability with guide rails across different accuracies, making it versatile for various applications where space is restricted in the transverse direction. Its patented entry zone enhances travel accuracy significantly, while its design supports long-term lubrication over several years. This ball runner block boasts excellent dynamic characteristics due to its optimized entry zone geometry and high number of balls, which also minimize variations in elastic deflection under load. It has integrated all-around sealing for protection against contaminants and supports minimum quantity lubrication systems. Suitable for use in demanding environments such as cleaning plants or electroplating lines due to its robust construction, this Rexroth ball runner block also finds applications in clean rooms and PCB manufacturing owing to its lack of additional corrosion protection requirements.
