The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-SNH-C1-N-1 (R162111420) is a high-precision ball runner block designed for linear motion applications where space is limited in the transverse direction, and high rigidity is required. This runner block is part of the Ball Rail Systems product group and offers significant rigidity compared to the SNS model, which makes it suitable for applications that demand maximum precision and rigidity with just one runner block per rail. The B.RUNNER BLOCK CS KWD-015-SNH-C1-N-1 features an unalloyed steel CS body with a low preload (preload class C) and standard accuracy (accuracy class N). It comes without a ball chain but includes initial lubrication and preservation, ensuring long-term lubrication over several years. The product has a straight lube connection loosely attached and does not include attachment elements on either front reference edge. With its patented entry zone, this runner block increases travel accuracy up to six times, offering excellent dynamic characteristics. It can handle high torque loads and operates smoothly and quietly due to its optimally designed ball return and guideway. This model can be used on all SN/SNO Ball Guide Rails, ensuring limitless interchangeability within each accuracy class of ball guide rail systems. The B.RUNNER BLOCK CS KWD-015-SNH-C1-N-1 is prelubricated at the factory, significantly reducing frictional oscillations and maintaining a low friction force level even under external load conditions. It has been designed for easy integration into various systems with an endface fastening thread for all attachments. Seals like the standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper are available to protect against contaminants such as dirt or metal particles, enhancing the service life of the runner block under different environmental conditions.
