The NSK LSFT series ball screw converts rotary motion into axial movement with minimal friction and high repeatability, making it a common choice for machine tools, automation equipment, and positioning systems that demand precision and rigidity. MR Industrial Accessories LLC supplies this series to customers throughout the United States and Latin America, offering guidance on selecting the appropriate configuration for your application.
The LSFT part number encodes the screw's nominal diameter and lead, separated by a hyphen. For instance, LSFT 2010-2.5 denotes a 20 mm diameter and a 10 mm lead, while LSFT 2516-2.5 indicates a 25 mm diameter and a 16 mm lead. The number following the hyphen—such as 2.5 or 3—specifies the count of ball circuits per nut, a factor that influences load capacity and rigidity.
These ball screws are found in machining centers, grinding machines, industrial robots, measuring equipment, and general automation. Industries such as automotive, metalworking, food processing, and packaging rely on them for precise, repeatable linear motion. They also appear in laser, plasma, and waterjet cutting machines, as well as in testing and laboratory devices.
When choosing a screw, consider axial load, rotational speed, the distance between supports, and allowable axial play. Lubrication—whether grease or oil—and proper nut sealing are critical to service life. During assembly, precise alignment of the supports and correct preload control are essential; improper installation can lead to vibration and premature wear. The LSFT series accommodates various nut and flange configurations to fit the available space.
NSK ball screws can be interchanged with those from other manufacturers when diameter, lead, length, and nut type align. To identify a compatible equivalent, compare the critical dimensions and load conditions. If you have a part number from another brand, send it to us and we will point you to the matching alternative. Custom screws can also be quoted when you provide the necessary machine data.

Frequently asked questions
- What does the suffix in the LSFT designation indicate?
- The suffix after the hyphen shows the number of ball circuits per nut, such as 2.5 or 3. This value affects load capacity and rigidity, so it is important for selecting the correct model.
- How can I request an equivalent for a ball screw from another brand?
- Send the complete part number of the screw you need to replace. We compare diameter, lead, length, and nut type to offer a compatible NSK alternative. Contact us via WhatsApp or email for a prompt quote.
- What should I keep in mind when assembling a ball screw?
- Proper alignment of the supports and controlled preload are essential. Use the recommended lubrication and sealing to keep contaminants out. Incorrect assembly can cause vibration and premature wear, so follow the manufacturer's guidelines.
