The NSK SFYD series ball screw converts rotary motion into precise linear travel, making it a core component in machine tools, automation and positioning systems. MR Industrial Accessories LLC supplies this series to maintenance and engineering teams across the United States, Canada, Mexico and South America, with support for selecting the right configuration for each application.
The SFYD part number breaks down into diameter, lead and nut configuration. For instance, SFYD 3210-5 indicates a 32 mm nominal diameter and 10 mm lead, while SFYD 4015-3 corresponds to 40 mm diameter and 15 mm lead. The final suffix, such as -5 or -3, identifies the number of ball circuits or the nut type, which affects load capacity and rigidity.
Typical applications include CNC machining centers, lathes, grinders, coordinate measuring machines and high-repeatability automation cells. These ball screws also appear in precision presses, manipulators and positioning tables. Their efficiency and low wear make them suitable for continuous cycles in metalworking, automotive and general manufacturing.
To specify an SFYD ball screw, evaluate axial load, critical speed, support spacing and allowable axial play. Installation requires precise support alignment, lubrication with grease or oil formulated for ball screws, and protection with bellows or seals to keep out chips and dust. Nut preload is a key factor in system rigidity and repeatability.
NSK ball screws may be interchangeable with other brands, but equivalence is not automatic. You must compare diameter, lead, nut type, preload and mounting dimensions. Send the original part number or the key measurements to our team via WhatsApp or email, and we will help you identify a compatible option.

Frequently asked questions
- What does the designation SFYD 3210-5 mean?
- SFYD identifies the ball screw series. The first digits, 32, are the nominal diameter in millimeters; the next, 10, is the lead in millimeters. The suffix -5 indicates the number of circuits or nut type. Each combination defines load and rigidity.
- How do I choose the right ball screw for my machine?
- You need the axial load, rotation speed, support spacing and allowable axial play. With that data, the diameter, lead and preload are defined. If you don't have the full data, send the original ball screw code or main measurements and we will advise you.
- Are NSK ball screws interchangeable with other brands?
- They may be compatible with other manufacturers, but interchangeability depends on matching diameter, lead, nut type, preload and mounting dimensions. Diameter and lead alone are not enough. Send us the original part code and we will indicate the equivalent.
