A ball screw from the NSK FA series turns rotary input into straight-line movement with minimal friction and consistent positioning. Machine tools, automated assembly stations and measurement systems rely on this kind of drive where accuracy and stiffness matter. MR Industrial Accessories supplies the FA series and assists with part number selection for your specific setup.
The part number tells you the main specs once you know how to break it down. Start with the letter W: that stands for the ball screw family. The next digits give the nominal diameter and lead. Then come the letters FA, which describe the nut style. After that, a number plus P shows the preload level, C followed by a digit is the accuracy class, and Z with a digit indicates how the returns are arranged. Take W1001FA-1P-C3Z4: 1001 is the diameter and lead, 1P is preload, C3 is accuracy, Z4 is the return. W1201FA-3P-C3Z5 changes the diameter and lead to 1201 and the preload to 3P. Other combinations exist, such as W1002FA-1P-C3Z4 or W1003FA-3P-C3Z4, but the series covers many more references.
Typical installations include machining centers, CNC lathes, grinding machines, coordinate measuring machines, Cartesian robots and test rigs. They also show up in material handling equipment and precision medical devices. Because these screws handle substantial axial loads while holding their accuracy, they suit demanding duty cycles.
When you pick a ball screw, look at the axial load, the speed, the overall length and how it will be mounted. The preload number before the P affects rigidity and axial play. The accuracy class, like C3 or C5, sets the allowed lead error. Sealing and lubrication are just as important: match the seal to the environment, whether that means dust, chips or coolant, and use the lubricant the maker recommends. Careful alignment between the screw and the linear guide prevents unnecessary stresses.
Ball screws from different manufacturers can sometimes be swapped if critical dimensions such as diameter, lead, length and mounting style line up. Accuracy classes and preloads, however, do not always translate directly from one brand to another. If you have a part number from another make, share it with us and we will help you find the closest match in the NSK range.

Frequently asked questions
- What does the designation W1001FA-1P-C3Z4 mean?
- W indicates ball screw; 1001 is the diameter and lead; FA is the nut type; 1P is preload; C3 is accuracy class; Z4 is return type. Each block defines a technical characteristic that influences performance.
- How do I choose between the 1P and 3P variants?
- Preload 1P and 3P differ in the level of rigidity and axial play. For applications requiring high precision, higher preload is usually preferred. We advise you according to your machine and working conditions.
- What should I take into account for mounting?
- Check alignment with the guide, the seal type according to the environment and the recommended lubrication. Incorrect mounting can cause vibration and premature wear. Follow the manufacturer's instructions.
