The NSK SFYD 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 market, with technical advice to choose the right configuration for your application.
The SFYD series designation is read in blocks: the letters identify the ball screw family, and the numbers that follow indicate nominal diameter and lead. For example, SFYD 3210-5 corresponds to a screw with 32 mm diameter and 10 mm lead, while SFYD 4015-3 has 40 mm diameter and 15 mm lead. The final suffix, such as -5 or -3, indicates the number of ball circuits or the nut type, a key detail for defining load capacity and rigidity.
In Argentine industry, SFYD ball screws are used in machining centers, CNC lathes, grinding machines, coordinate measuring equipment and automation systems with high repeatability requirements. They also appear in precision presses, manipulators and positioning tables. Their ability to run at high speeds with low wear makes them suitable for continuous cycles in metalworking, automotive and capital goods production.
To select an SFYD ball screw, consider the axial load, critical speed, length between supports and permissible axial play. Installation requires precise alignment of the supports, lubrication with grease or oil specifically for ball screws, and protection of the assembly with bellows or seals to prevent contamination from chips or dust. Nut preload directly influences the rigidity and repeatability of the system.
NSK ball screws can be interchanged with those from other leading manufacturers, but the equivalence is not automatic: you must compare diameter, lead, nut type, preload and mounting dimensions. At MR Accesorios Industriales we advise you to find the option compatible with your equipment, whether you bring the original code or a sample of the part.
If you need an SFYD series ball screw, write to us on WhatsApp with the code or the measurements shown on your equipment. We will quote the exact reference and indicate the compatible alternative if applicable. MR Accesorios Industriales, Buenos Aires, Argentina, more than 80 years supporting industry.

Frequently Asked Questions
- What does the designation SFYD 3210-5 mean?
- The letters SFYD identify the ball screw series. The first digits, 32, indicate the nominal diameter in millimeters; the next, 10, the lead in millimeters. The suffix -5 refers to the number of circuits or the nut type. Each combination defines load and rigidity.
- How do I choose the right ball screw for my machine?
- You need to know the axial load, rotation speed, length between supports and permissible axial play. With that data, the diameter, lead and preload are defined. If you do not have the information, send us the original ball screw code or the main measurements and we will advise you.
- Are NSK ball screws interchangeable with other brands?
- They may be compatible with those from other manufacturers, but interchangeability depends on matching diameter, lead, nut type, preload and mounting dimensions. Diameter and lead alone are not enough. Bring us the original part code and we will indicate the equivalent.
