The NSK LSFT series ball screw is a linear transmission component that converts rotation into axial displacement with high efficiency and repeatability. It is used in machine tools, automation equipment and positioning systems where precision and rigidity are critical. MR Accesorios Industriales sells this line for the Argentine industrial market, with technical advice to choose the right configuration for the application.
The LSFT series designation is read in blocks: the main number indicates the nominal diameter and the lead, and the numeric suffix with the word Clearance defines the axial clearance or preload. For example, LSFT 4025-2.5Clearance corresponds to a screw with a 40 mm diameter and 25 mm lead with a specified clearance, while LSFT 4032-2.5Clearance and LSFT 4040-1.5Clearance vary the lead and the clearance value. These part numbers make it possible to quickly identify the geometry and the fit required for each piece of equipment.
In Argentine industry, LSFT ball screws are used in machining centers, CNC lathes, grinding machines, precision presses, measuring equipment and industrial automation systems. They are also used in laser cutting machines, high-resolution printing and manipulators that require smooth, backlash-free movements. Their ability to withstand high axial loads with low friction makes them suitable for intensive work cycles in continuous production plants.
To select the right screw, take into account the axial load, rotation speed, length between supports and required clearance. Mounting requires precisely aligning the supports and guides, and lubricating with grease or oil specifically for ball screws. Proper sealing prevents particle contamination and extends service life. The preload or clearance indicated in the part number determines rigidity and repeatability, so it is advisable to respect the manufacturer's original specification.
NSK LSFT series ball screws can be interchanged with equivalent products from other brands, provided the diameter, lead, length, nut type and clearance match. It is not enough to match only the diameter and lead: the mounting interface, load capacity and recirculation type must be verified. If you have another brand's part number, we can help you find the compatible reference or the alternative that best suits your machine.
If you need an LSFT ball screw for your equipment, send us the part number or dimensions by WhatsApp and we will quote it shortly. At MR Accesorios Industriales we advise you so that you choose the right configuration and we indicate the compatible alternative if needed. Write to us with the data of your application and we will reply with a technical proposal.

Frequently Asked Questions
- What does the Clearance suffix mean in the LSFT series?
- The Clearance suffix indicates the axial clearance or preload of the screw. The associated numeric values, such as 2.5 or 1.5, define the magnitude of that clearance according to the manufacturer's specification. It is a key data point for the rigidity and repeatability of the system.
- How do I know which LSFT screw my machine needs?
- You need the diameter, lead, total length, nut type and required clearance. If you have the original part number, send it by WhatsApp and we will quote the exact reference. If not, we can guide you with the data of your application.
- Can I replace a screw from another brand with an NSK LSFT?
- Yes, provided the critical dimensions match: diameter, lead, length, mounting interface and clearance. It is not enough to match only the diameter and lead. If you send us the original part's part number, we will indicate the compatible equivalence.
