Product Description

Product Description

The Rexroth B.RUNNER BLOCK CS KWE-025-SNS-C1-H-1 (R205C21320) is a high-precision linear motion component designed for applications requiring compact size and high load capacity. This BSCL ball runner block features a slimline, normal, standard height (SNS) format and is constructed from unalloyed steel CS. It offers low preload (class C) and high accuracy (class H), ensuring smooth motion and precise positioning. The runner block body is of the standard version with an overall length of . mm, allowing for interchangeability with guide rails of every accuracy level. The product is suitable for use in environments with restricted space in the transverse direction and can be mounted from above. It boasts a high load capacity, making it ideal for various demanding applications. This model does not come with a ball chain but includes initial lubrication and preservation to maintain performance over time. The permissible ambient temperature range for this runner block extends from min ... max °C, which can withstand short periods outside this range. The friction coefficient without seal friction is specified between . and . Key specifications include a static load rating C0, dynamic load capacity C, dynamic longitudinal moment load capacity ML, static torsional moment load capacity Mt0, dynamic torsional moment load capacity Mt, as well as dimensions that cater to various profiled rail systems including sizes B, H, K, N, S, T and E. The product also features a standard seal SS and has been assigned the product group ID . With its robust design and versatile application potential, the Rexroth B.RUNNER BLOCK CS KWE-025-SNS-C1-H-1 (R205C21320) runner block is an essential component for linear motion systems requiring precision under high-load conditions.
