The Bosch Rexroth B.RUNNER BLOCK CS KWC-055-FLS-C3-U-2 (R165353910) is a sophisticated linear motion component designed for the most demanding applications requiring ultra-precision and high preload. This ball runner block is part of the Ball Rail Systems product group, which offers a smooth, quiet operation with minimal friction due to its four rows of balls and point contact in all loading directions. The runner block body is constructed from unalloyed steel CS, ensuring durability and robustness. With an accuracy class UP (Ultra Precision), this runner block meets the requirements for applications that demand extremely precise movement control. The high preload class C indicates that the component has been pre-tensioned to a higher degree to reduce system clearances and increase rigidity. It is also preserved but comes without initial lubrication, allowing users to apply their preferred lubrication method. Designed without a ball chain, the R165353910 model ensures easy handling and maintenance. Its flanged long standard (FLS) format provides additional stability and can be easily integrated into various machine designs. The angular lube nipples are loosely attached for convenient lubrication access. The interchangeability feature of this runner block allows it to be combined with any guide rails within the system, regardless of accuracy class, offering flexibility in design and replacement. It has been engineered to withstand heavy loads and provide maximum rigidity in all load directions, making it ideal for heavy-duty machine construction. This model includes additional features such as innovative channel design for minimum lubrication requirements, optimized ball return and guideway for smooth operation, and optimized entry-zone geometry that minimizes variation in elastic deflection under load. Attachments can be mounted from both above and below the runner block due to its end-face fastening thread design. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWC-055-FLS-C3-U-2 (R165353910) represents a high-performance solution for linear motion applications where precision, rigidity, and interchangeability are critical factors.
