The Bosch Rexroth B.RUNNER BLOCK CR KWC-020-SKN-VC (R030100469) is a high-precision linear motion component designed to minimize friction and ensure smooth, accurate movement in various applications. This runner block features a unique Rexroth design incorporating four rows of balls, providing point contact in all loading directions and significantly reducing friction. This design advantage allows for minimal differential slip even under lateral loads or when pre-stressed without load, resulting in lower heat generation compared to other ball rail systems with gothic raceway profiles. Equipped with universal standard seals (SS), the B.RUNNER BLOCK CR ensures excellent protection against contaminants such as dirt, chips, and coolants, thus extending its service life. The seal design strikes a balance between low friction and effective sealing, suitable for a wide range of applications. For environments demanding reduced frictional resistance, the low-friction seal (LS) variant is available, while the double-lip seal (DS) offers enhanced protection against media exposure. For more challenging conditions involving fine dirt or metal particles and heavy usage of coolants or cutting fluids, the FKM seal option provides robust protection. Both front seals and FKM seals are designed to be interchangeable during servicing, adding to the maintenance convenience. Additionally, for environments with coarser dirt or chips presence, customers can opt for the cover plate wiper accessory that can be mounted as needed. The B.RUNNER BLOCK CR KWC-020-SKN-VC is versatile enough to cater to special requirements while maintaining ease of movement and reliability across various industrial applications. Its advanced sealing options ensure that it can operate effectively even in extreme conditions without compromising performance.
