For linear motion that demands accuracy and repeatability, the NSK LDFT series ball screw is a proven choice. It turns rotary input into axial movement efficiently. You will find these screws in machine tools, automation systems and measuring equipment. MR Industrial Accessories provides this line to customers in the United States and Latin America, and can quote the exact part number or size you specify.
Reading an LDFT part number is straightforward once you know the pattern. The letters indicate the series and design. The first two digits after the letters give the nominal screw diameter, and the next two digits give the lead. The suffix shows how many ball circuits are inside the nut. For instance, LDFT 4025-2.5D has a 40 mm diameter and a 25 mm lead with 2.5 circuits. LDFT 4032-2.5D and LDFT 4040-1.5D follow the same logic but with different diameter and lead values. These numbers determine load capacity and critical speed.
Typical applications for LDFT ball screws include machining centers, grinding machines, industrial robots and general automation. They are common in metalworking, automotive and capital goods production where smooth motion without backlash is essential. MR Industrial Accessories supplies them for both replacement and new builds.
When selecting a ball screw, review the axial load, rotational speed, unsupported length and mounting method. Correct lubrication and sealing keep contaminants out and help the screw last. Make sure the screw and nut are aligned to prevent side loads. If a nut is included, check the preload and axial clearance for your application.
NSK ball screws can often replace units from other makers when diameter, lead, length and nut type are compatible. Comparing key dimensions and load ratings is the best way to find an equivalent. If you have a part number from another brand, send it and we will identify a matching option. We can also quote directly from the dimensions on your drawing.

Frequently asked questions
- What does the LDFT 4025-2.5D code indicate?
- The LDFT prefix identifies the series. The numbers 40 and 25 are the diameter and lead in millimeters. The 2.5D suffix shows the number of ball circuits. Together these define load and speed characteristics.
- How do I select the correct ball screw for my machine?
- Start with the axial load, speed, length between supports and mounting style. Also consider the required precision. With those details, we can help you choose the LDFT model that fits your application.
- Can I use an NSK LDFT screw to replace a different brand?
- Often yes, if diameter, lead, length and nut type match. Mounting dimensions and load capacity are key to interchangeability. Send us the original part number and we will suggest an equivalent or quote the exact size.
