The NSK NH series is a precision steel linear guide rail that works together with matching carriages to provide controlled, low-friction movement on industrial machinery. It is specified where stiffness and repeatable positioning matter, including machining centers, robotic systems, measuring stations and automated production lines. MR Industrial Accessories LLC supplies this series in a range of sizes and helps buyers identify the correct rail and carriage combination for their equipment.

Reading the code is the first step in selection. In designations such as NH15BN, NH20BN, NH25BN, NH30BN, NH35BN, NH45BN, NH55BN and NH65BN, the figure in the middle is the nominal size of the rail: 15, 20, 25, 30, 35, 45, 55 or 65. The BN ending denotes a construction variant inside the series. Because each rail size accepts several carriage types, the carriage is chosen based on the load and the moment the assembly has to carry.

Typical users are machine tool builders, automation integrators and plants in metalworking, food and beverage, pharmaceutical and general manufacturing. Common installations include machining centers, cutting gantries, palletizing robots, inspection tables and test rigs. The profile design supports stiff, repeatable assemblies, which is why these rails appear in processes where dimensional accuracy is critical.

When specifying a rail, review the static and dynamic load, the tilting moment and the rigidity the application demands. The mounting surface should be ground and aligned, and flatness and parallelism are worth checking before the profile is fastened down. Correct lubrication, together with sealing against dust and chips, protects service life. In dirty or aggressive environments, protective caps and bellows are available as add-ons.

Rails from different manufacturers can often be exchanged when mounting dimensions, height and hole spacing line up. Square profile series in particular tend to share dimensional compatibility across brands, but the load capacity and stiffness of the carriage still have to be confirmed. If you are working from another maker's part number, our team can help you locate a suitable equivalent.
