The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C1-P-1 (R162121220) is a high-precision ball runner block designed for linear motion on ball guide rails. This model features a slim, normal, high (SNH) format with an overall length of the runner block at . mm. It is constructed from unalloyed steel CS and offers low preload (class C) and high precision (accuracy class P), without a ball chain. The product is prelubricated with Roller bearing grease Dynalub for initial use and has provisions for long-term lubrication. Its design allows for smooth, quiet operation due to an optimally designed ball return and guideway, with a patented entry zone that enhances travel accuracy up to six times. The dynamic characteristics of this runner block are excellent, capable of handling high rigidity requirements in restricted spaces transversely while providing higher rigidity than SNS models. It also boasts reduced frictional oscillations and a low friction force level, particularly under external loads. This runner block can be utilized in various applications due to its high torque load capacity and compatibility with all SNSSNO ball guide rails within each accuracy class. The product's interchangeability feature ensures it can be combined freely with any guide rail system in its class. Additionally, it supports different preload classes to suit various application needs. The B.RUNNER BLOCK CS KWD-025-SNH-C1-P-1 is equipped with an endface fastening thread for attachments and operates efficiently within a permissible ambient temperature range of min ... max °C. Its static load rating C0 and dynamic load capacity C are determined based on DIN ISO standards to ensure reliability during operation. The runner block's dimensions include a width of . mm for size E profiled rail systems and a length of . mm, making it suitable for diverse industrial applications where precision linear movement is critical.
