DIN 631:2025-08

This standard specifies the test parameters for the verification of the dynamic load rating of ball carriage or roller carriage profiled rail guides in accordance with DIN ISO 14728-1. This standard is exclusively intended for experimental verification of the dynamic load rating of ball carriage or roller carriage profiled rail guides, hereinafter referred to as profile rail guides. The indication of the dynamic load rating in accordance with DIN ISO 14278-1 in connection with the clearly defined influencing factors b_m and λ serves as the basis. This document is not applicable for the experimental determination of a dynamic load rating. For example, the design and arrangement of the test setup are not included in this document. In addition, the scope of testing described in this document is not sufficient for the experimental determination of a dynamic load rating. This document has been prepared by Working Committee NA 118-01-11 AA "Linear-Wälzlager einschließlich Teile und Zubehör" ("Linear motion rolling bearings including parts and supplies") at DIN Standards Committee Rolling Bearings and Plain Bearings (NAWGL).
