NSK NH series linear guides are precision components that keep carriages and heads moving smoothly and repeatably. They are at home in machine tools, automation equipment, machining centers and other systems where travel has to be consistent. MR Industrial Accessories supplies this line to customers across the United States and in several Latin American countries, and can help you pick the right guide for the job. If you already know the part number, send it over and we will quote it.
The code is easy to read once you know the pattern. NH marks the family, the number after it gives the nominal size, and the EM suffix covers precision and preload. So NH15EM, NH20EM and NH25EM are simply different sizes in the same series. A larger number means a wider guide with more load capacity. The EM ending stays the same across the range and reflects a standard setup for the series.
You will find these guides in metalworking, automation, packaging, food processing and pharmaceutical operations. They appear on machining centers, Cartesian robots, coordinate tables, inspection equipment and assembly lines. Their job is to guide carriages and heads accurately, take loads from different directions and hold positioning repeatability.
When selecting an NH guide, look at the load it will carry, the rigidity you need, travel speed and the surrounding conditions. The mounting surface must be flat and aligned, and the screws need a controlled tightening torque. Good lubrication and sealing against dust or chips help the guide last. In dirty environments, consider extra protection. We can walk you through these points.
Guides from different brands can sometimes be swapped if mounting dimensions, height and rail type line up. A similar part number is not enough; you have to check geometry and load capacity. If you bring us a number from another brand or an unidentified part, we will identify the compatible equivalent and quote the option that fits your equipment.
To get a quote, send the full part number on WhatsApp, for example NH30EM or NH45EM. A photo or drawing of the carriage and rail also works. We reply promptly so you can evaluate the purchase.

Dimensions and tolerances: Message us the part number on WhatsApp and we'll verify its dimensions and version with the manufacturer's datasheet.
Frequently asked questions
- What does the EM suffix mean on NSK NH series guides?
- The EM suffix indicates a standard configuration within the NH series, tied to precision and preload. It does not change the nominal size, which is given by the number. For the exact meaning, check the full designation on the drawing or equipment nameplate.
- How do I know what size of NH guide I need?
- Size depends on load, rigidity and mounting space. The number in the part number (15, 20, 25, etc.) is the nominal size. If you are unsure, send us the rail and carriage measurements and we will help you define the right option.
- Can I replace a guide from another brand with an NSK NH series guide?
- Yes, if the mounting dimensions, height and load capacity match. A similar part number alone is not enough. Send us the original part number or the main measurements and we will tell you the compatible equivalent within the line we supply.
