Linear rails are typically made from hardened carbon chrome steel (e.g., SUJ2/52100) or stainless steel (e.g., SUS440C). The surface hardness is 58–62 HRC. Material grades may be specified as GCr15 or 100Cr6 per GB/T 18254 and EN ISO 683-17. Always confirm the exact material with the manufacturer for your application.
Accuracy grades range from C1 (highest precision) to C5 (standard) per ISO 12090-1. Running parallelism is 0.003–0.02 mm per 1000 mm length. The appropriate grade depends on the required positioning accuracy of your application.
Dynamic load ratings range from 5 to 120 kN, and static load ratings from 10 to 250 kN, both per ISO 14728-1. These values are reference ranges; the actual load capacity depends on the specific rail size, preload, and mounting conditions. Verify with the manufacturer.
Regular lubrication is essential. Grease is standard, but oil can be used. The operating temperature range is -40 to 85 °C. Wipers and seals provide IP54–IP65 protection. Inspect for wear, contamination, and proper preload periodically. Follow the manufacturer's maintenance guidelines.
