The NSK FSS series ball screw turns rotary input into axial movement for linear axes that need smooth operation and repeatable positioning. You will find it in machine tools, automation cells and positioning stages. MR Industrial Accessories supplies this series to customers across the United States and Latin America and can help match the right configuration to your machine.
Reading the code helps you order the correct screw. FSS is the series. The digits that follow give the nominal diameter and then the lead, so FSS1210 is a 12 mm diameter screw with 10 mm lead, and FSS1510 is 15 mm diameter with 10 mm lead. The next block, such as N1, covers nut type and preload. The suffix D plus a number, for example D0400, states the overall length in millimeters. Put together, FSS1210N1D0400 is a 12 mm diameter screw, 10 mm lead, N1 nut, 400 mm long.
Typical applications include machining centers, grinding machines, coordinate measuring machines, Cartesian robots and test stands. Shops producing auto parts, capital equipment and automated devices rely on this series where accuracy must hold up over long run times. Low wear at higher speeds makes it a fit for continuous cycles.
Selection comes down to axial load, speed, required accuracy and the operating environment. Nut preload affects rigidity and axial clearance, while sealing keeps particles out and lubricant in. Grease or oil lubrication, applied correctly, supports service life. Align the screw with the linear guide to avoid parasitic loads, and follow the support configuration instructions during assembly.
Interchange with other brands is possible, but only when the critical dimensions line up: diameter, lead, length, nut type and precision class. Confirm that tolerances and load capacity are compatible before substituting. If you are replacing a screw from another maker, our team can help you identify a suitable alternative.

Frequently asked questions
- What does the code FSS1210N1D0400 tell me?
- FSS is the series, 12 is the nominal diameter in mm, 10 is the lead in mm, N1 is the nut type and preload, and D0400 is the total length in mm. Send us the full code and we can confirm the configuration.
- Can this screw handle high-precision positioning?
- Yes, the FSS series is built for accurate positioning. Preload, sealing and correct lubrication all influence repeatability. Share your machine specifications and we will help you choose the right model.
- Can I replace a screw from another brand with an NSK FSS unit?
- Often yes, but you must compare diameter, lead, length, nut type and precision. Send the original part code or your measurements and we will point you to a compatible equivalent and quote it.
