The NSK DH series linear guide is a linear motion component that allows smooth and precise travel with high rigidity. It is used in machine tools, automation equipment and positioning systems where accuracy and repeatability are critical. MR Accesorios Industriales sells this series in different sizes so you can solve your application with the backing of a leading brand.
The DH series designation is read with the number that indicates the size and the EM suffix that identifies construction characteristics. For example, DH15EM, DH20EM and DH25EM correspond to different guide sizes, while the EM suffix remains throughout the series. The higher the number, the greater the load capacity and the overall size of the assembly. To choose the right model, take into account the mounting dimensions and the rigidity requirements of your equipment.
These linear guides are used in a wide variety of industries in Argentina, such as metalworking, automotive, food and pharmaceutical. They are present in machining centers, industrial robots, inspection equipment and precision transport systems. Their design allows smooth motion even at high speeds, with low friction and reduced wear, which makes them suitable for applications that demand continuous cycles and high reliability.
To select the right guide, consider the load it must support, the operating speed and the environmental conditions. It is essential to verify the alignment of the rails and the parallelism between them to avoid unnecessary stresses. Proper lubrication and sealing against contaminants extend the service life of the system. During mounting, follow the manufacturer's recommendations regarding tightening torque and axial clearance. If you need advice, our technical team can help you.
Linear guides of the DH series can be interchanged with equivalent products from other brands, but it is important to verify the mounting dimensions and load capacities before replacing an existing guide. MR Accesorios Industriales can tell you the compatible alternative if you provide us with the part number of the original part or the relevant measurements. Do not hesitate to contact us with any compatibility question.

Frequently Asked Questions
- What does the EM suffix mean in the DH series?
- The EM suffix identifies specific construction characteristics within the DH series, such as the cage type or the ball material. It remains constant across all sizes, from DH15EM to DH65EM. For precise technical details, contact us with the complete part number.
- How do I choose the right DH linear guide size?
- The size is selected according to load, speed and mounting space. Higher numbers (for example, DH45EM or DH55EM) offer greater load capacity. We recommend evaluating the dimensions of the rail and the block, and contacting us for a recommendation tailored to your equipment.
- Can I replace a guide from another brand with an NSK DH?
- In many cases yes, but the mounting dimensions, load capacity and preload must be verified. If you send us the part number of the original guide or the measurements, we will tell you the equivalent NSK reference and quote it for you on WhatsApp.
