The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-FNS-C0-H-0 (R200129306) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications requiring high rigidity and accuracy. This runner block features size 25 with an FNS format, indicating a flange width, normal length, and standard height. It is constructed of Resist NRII material which makes it suitable for environments with corrosive elements such as water-based media or saline solutions. The runner block boasts a high accuracy class H and is preload-free with preload class C. It includes a ball chain that contributes to low noise levels and optimal travel behavior. The product does not require initial lubrication or preservation upon delivery, making it ready for use in clean room conditions or in general printed circuit board manufacturing without additional preparation. This model has an overall length of 70.2 mm and can be used interchangeably with guide rails to meet various application requirements. The dynamic load capacity C, static load rating C0, and the dynamic torsional moment load capacity Mt are determined based on a 100,000 m travel as per DIN ISO norms. Designed without self-alignment features, the B.RUNN. BLOCK NRII KWD-025-FNS-C0-H-0 is equipped with standard SS seals to prevent contamination from dirt or coolants and ensure prolonged service life under challenging conditions. Its optimized entry-zone geometry coupled with the high number of balls reduces elastic deflection variance. This Bosch Rexroth ball runner block is ideal for applications where maximum precision and durability are essential, such as in automation equipment, machine tools, and heavy-duty industrial machinery that operates under corrosive conditions or requires long-term lubrication over several years.
