The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-SNS-C1-N-1 (R162281423) is a high-precision ball runner block designed for linear motion applications where space is restricted in the transverse direction and high torque load capacity is required. This ball runner block offers the same high load ratings in all four main directions of loading, and its optimized entry-zone geometry combined with a high number of balls ensures minimal variation in elastic deflection. Constructed with an unalloyed steel CS body, the B.RUNNER BLOCK CS features a slimline width, standard height, and normal length (SNS format). It comes with a low preload (Preload class C) and standard accuracy class N. The ball chain integrated into the design contributes to low noise levels and smooth travel behavior. Additionally, this model includes initial lubrication with roller bearing grease Dynalub for long-term use over several years without frequent maintenance. The runner block body has an end-face fastening thread for attachments and can be mounted from above. It also boasts integrated all-around sealing to protect against contaminants, which extends its service life. The minimum quantity lubrication system with an integrated reservoir allows for oil lubrication when needed. This product can be used interchangeably on all SNS/SNO ball guide rails within each accuracy class, featuring excellent dynamic characteristics suitable for various applications. The prelubricated ball runner block ensures immediate operation upon installation. Its design allows for self-aligning to compensate for any misalignments during use. Key specifications include a dynamic load capacity C determined as per DIN ISO standards, static load rating C0, dynamic torsional moment load capacity Mt, and permissible ambient temperatures ranging from minimum to maximum degrees Celsius. The product group ID indicates its categorization within Bosch Rexroth's extensive range of linear motion products.
