For machine tools, automation equipment and positioning systems that depend on smooth, repeatable linear motion, the NSK SFT series ball screw is a proven choice. It converts rotation into axial travel with the efficiency and rigidity that precision work demands. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the United States and Latin America.

The SFT part number tells you the main dimensions. The first digits after SFT are the nominal diameter in millimeters, the next digits are the lead, and the number before the word Clearance is the axial clearance in microns. So SFT 4510-5Clearance is a 45 mm diameter screw with a 10 mm lead and 5 microns of clearance. SFT 4512-2.5Clearance is also 45 mm in diameter but has a 12 mm lead and 2.5 microns of clearance. The Clearance value directly affects how precise and rigid the assembly will be.

You will find these screws in machining centers, CNC lathes, grinding machines, coordinate measuring machines, industrial robots and general automation. They are also common in metalworking, automotive, food and packaging plants, as well as in laboratory and medical equipment where accurate, repeatable positioning is essential.

When specifying a screw, review the axial load, rotation speed, required precision and the operating environment. A smaller clearance gives more rigidity and accuracy, but it also raises friction and heat, so alignment and lubrication become more critical. Proper support alignment, adequate lubrication and protection from contaminants with seals or bellows all influence service life. Nut type and preload also play a role in performance.

NSK SFT ball screws can replace equivalent products from other manufacturers when diameter, lead, axial clearance and nut type match. Always confirm mounting dimensions and load capacity before ordering. If you only have another brand's part number, send it to us and we can help identify the right equivalent.
