The NSK LDFT series covers ball screws that turn rotation into axial movement for positioning and linear motion duties. You will find them in machine tools, automation cells and measuring setups where repeatability and rigidity matter. MR Industrial Accessories LLC supplies this series to customers in the United States and Latin America, and can review the part number with you before you commit to a size.
The code tells you the main dimensions. In LDFT 2516-2.5, the first pair of digits is the nominal diameter, 25 mm, and the second pair is the lead, 16 mm. In LDFT 2520-3, the same 25 mm diameter is paired with a 20 mm lead. The figure after the hyphen is the count of ball circuits in the nut, which drives load capacity and how rigid the assembly feels. Reading the code this way lets you compare variants without opening a catalog.
Typical applications include machining centers, CNC mills, grinders, Cartesian robots and measuring equipment, as well as precision presses, laser cutters and automated transport lines. The low friction and ability to take axial load suit plants running heavy duty cycles in metalworking, automotive and food processing.
Selection starts with axial load, rotational speed, the distance between supports and the axial play you can accept. Mounting calls for aligning the supports with the travel axis and applying the right lubricant, grease or oil depending on the duty. The nut seal keeps contaminants out and helps the screw last. Preload also changes rigidity and repeatability, so decide it early.
LDFT ball screws can be replaced with other makes that use similar diameter and lead figures, but check tolerances and nut type first. If you only have another brand's number or an unmarked part, send the details and we will point you to a compatible equivalent. MR Industrial Accessories LLC supplies the LDFT series and quotes the exact size you ask for.
To get a quote, send the full part number by WhatsApp, for example LDFT 3220-2.5, or give us the diameter and lead. We will reply promptly and can also advise on lubrication and installation.

Frequently asked questions
- What does the suffix in an LDFT ball screw mean?
- The number after the hyphen is the count of ball circuits per nut. It sets load capacity and rigidity: more circuits mean higher capacity and a longer nut.
- How do I choose between a 16 lead and a 20 lead?
- Lead is the travel per revolution. A larger lead gives higher speed but lower resolution; a smaller lead gives more precision and force. Match it to the speed and load of your application.
- What lubrication does an NSK ball screw need?
- Grease or oil, depending on speed and environment. Grease is common in normal applications, while oil suits high speeds or elevated temperatures. Follow the relubrication interval recommended for your setup.
