The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C0-N-0 (R201189406) is a high-quality ball runner block designed for precision linear motion applications. This product belongs to the Ball Rail Systems and is characterized by its Resist NRII construction, which makes it corrosion-resistant and suitable for use in environments with water-based media or high humidity. It features size SNS dimensions, indicating a slim width, normal length, and standard height profile. The runner block body and all steel components are crafted from corrosion-resistant steel as per DIN EN standards, ensuring durability and long-term performance. It is preload-free (preload class C) with standard accuracy class N, offering reliable motion without pre-tensioning. The inclusion of a ball chain contributes to low noise levels and smooth travel behavior. This model does not come with initial lubrication or preservation, providing flexibility for users to apply their preferred lubricants according to application needs. It also lacks attachment elements on both the left and right front reference edges but includes a straight lube connection that is loosely attached. The B.RUNN. BLOCK NRII KWD-020-SNS-C0-N-0 boasts an overall runner block length of 70 mm and supports interchangeability across guide rails of varying accuracies. It's designed for spaces restricted in the transverse direction and offers the possibility of long-term lubrication extending over several years. In terms of load handling capabilities, this model maintains high load ratings in all four main directions of loading due to its design featuring an optimized entry zone geometry that enhances travel accuracy significantly—up to six times—and reduces elastic deflection variation. The dynamic characteristics are excellent thanks to the high number of balls within the system. With integrated all-around sealing, this product ensures protection against contaminants while maintaining efficient operation even under external loads. Its maximum permissible ambient temperature ranges from -10°C up to 80°C for short periods, making it versatile for various working environments. The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C0-N-0 (R201189406) stands out as a robust solution for linear motion requirements where precision, corrosion resistance, and low maintenance are critical factors.
