For machine tools, automation cells and positioning axes that demand accurate, repeatable linear movement, the NSK LSFT series ball screw turns rotation into axial travel. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and several Latin American countries, and can help you pin down the right configuration for your application.
Reading an LSFT part number is straightforward once you know the blocks. The main figure pairs nominal diameter with lead, and the numeric suffix tied to the word Clearance sets the axial clearance or preload. Take LSFT 4025-2.5Clearance: 40 mm diameter, 25 mm lead, with a defined clearance. LSFT 4032-2.5Clearance and LSFT 4040-1.5Clearance change the lead and clearance values. These codes let you identify geometry and fit at a glance.
Typical applications include machining centers, CNC lathes, grinding machines, precision presses, measuring equipment and industrial automation. You will also find them in laser cutting machines, high-resolution printing and manipulators where smooth, backlash-free motion is required. Their capacity to carry high axial loads with low friction suits intensive work cycles in continuous production plants.
When selecting a screw, consider axial load, rotation speed, length between supports and required clearance. Installation calls for precise alignment of supports and guides, plus lubrication with grease or oil intended for ball screws. Effective sealing keeps particles out and helps extend service life. The preload or clearance in the part number governs rigidity and repeatability, so staying with the original specification is advisable.
NSK LSFT ball screws can interchange with equivalent products from other brands when diameter, lead, length, nut type and clearance all match. Matching diameter and lead alone is not enough: verify the mounting interface, load capacity and recirculation type. If you have a part number from another brand, we can help you find the compatible reference or the alternative that best fits your machine.

Frequently asked questions
- What does the Clearance suffix mean in the LSFT series?
- It indicates the axial clearance or preload of the screw. Numeric values such as 2.5 or 1.5 define the magnitude of that clearance according to the manufacturer's specification. This is a key data point for system rigidity and repeatability.
- 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 your application data.
- 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. Matching only diameter and lead is not enough. If you send us the original part's part number, we will indicate the compatible equivalence.
