The NSK DH series linear guide is a linear motion component built for smooth, precise travel with high rigidity. It suits machine tools, automation equipment and positioning systems where accuracy and repeatability matter. MR Industrial Accessories LLC supplies this series to customers across the United States and in several Latin American countries, and helps you define the right configuration for your application.

Reading a DH series code starts with the number, which identifies the nominal dimension of the guide, followed by the AL suffix that marks a specific variant within the family. Codes in this series point to larger sizes of the same group. Because the suffix is not a universal convention, the reliable way to confirm what your reference means is to have a specialist check it against the exact equivalent.

Typical applications include automotive, metalworking, food and pharmaceutical operations, plus automation equipment, machining centers, Cartesian robots and precision conveying systems. They also appear in production lines that repeat movements with minimal friction and controlled wear, and in measuring machines where structural rigidity directly affects process quality.

Selection depends on load capacity, required rigidity, operating speed and environmental conditions. Mounting calls for a ground support surface and careful alignment between rails to avoid parasitic stresses. Use the lubrication specified by the manufacturer and renew it according to use. Sealing keeps contaminants out, and in dusty or chip-filled areas additional protection is advisable. Incorrect mounting shortens the service life of the system.

Guides from different brands can be interchanged when mounting dimensions, load capacity and rolling type match. A similar code is not enough: tolerances, preload and rigidity must be verified. When replacing an existing guide, send the part number of the original part or the main dimensions, and we will identify the compatible alternative or quote the exact reference you need.

If you have the part number for your NSK DH series linear guide, send it by WhatsApp or email and our team will reply promptly. We can also assist if you are replacing a guide from another brand or are unsure about the configuration.
