A ball screw from the NSK SFT series turns rotary input into straight-line travel, which makes it a common choice for positioning work that calls for accuracy and stiffness. You will find these screws in machine tools, automated equipment and similar motion systems. MR Industrial Accessories LLC supplies this series to customers across the United States, Canada, Mexico and South America, and can help you settle on the right configuration.

Reading the code tells you most of what you need. In SFT 2006-2.5, the first figure is the nominal diameter, 20 mm, the second is the lead, 6 mm, and the 2.5 after the hyphen counts the ball circulation turns. SFT 2504-5 works the same way: 25 mm diameter, 4 mm lead, 5 turns. SFT 2008-3 and SFT 2505-3 follow the identical pattern, so diameter, lead and turn count can be identified at a glance.

Typical installations include machining centers, CNC lathes, grinders, coordinate measuring machines, Cartesian robots and test rigs. They also appear in metalworking shops, auto parts plants, food processing facilities and laboratories where motion has to stay smooth and repeatable. The ability to carry heavy axial loads while holding accuracy suits them to demanding duty cycles.

When specifying, weigh the axial load, running speed, distance between supports and how the screw will be mounted. Lubrication and protection from contamination have a direct effect on service life. Coupling to the motor and alignment with the linear guide need attention to keep vibration down. Axial play and preload follow from the precision your application requires. MR can walk you through the mounting arrangement and the accessories that go with it.

Interchange with other major manufacturers is often possible when diameter, lead, length, nut style and precision class line up. Series from THK, HIWIN and Bosch Rexroth frequently share standardized dimensions, though tolerances and mounting details should always be checked. Give us the code from another brand and we will point you to the matching alternative or quote the NSK screw itself.

For a quote, send the full SFT code by WhatsApp or email together with the overall length and the end machining required. Nuts, supports and mounting accessories can be included in the same request. The team replies promptly with the technical and commercial details you need, and can suggest equivalents when a direct match is not available.
