MR Accesorios Industriales sells this line for the Argentine market and advises you on selection according to your application.

The FS series designation combines letters and numbers that identify nominal diameter, lead and nut type. For example, W1001FS-1-C3T4 indicates a screw with 10 mm diameter, lead 1, single nut and C3 precision. In W1202FS-2-C5T10, the 12 corresponds to diameter, 02 to lead, 2 to double nut and C5 to precision class. The T4 or T5 suffix refers to the return or preload type. These codes allow you to order exactly the screw your machine needs.

In Argentine industry, NSK FS series ball screws are used in machining centers, CNC lathes, grinding machines, coordinate measuring machines, laser cutting equipment and industrial automation systems. They are also present in the food, pharmaceutical and automotive industries, where smooth, maintenance-free motion is required. MR Accesorios Industriales sells them for production plants and workshops looking for reliable spare parts.

To select the right screw, consider axial load, rotation speed, required precision and mounting type. The FS series supports different precision classes, from C3 to C5, and different nut types depending on preload. Sealing and lubrication are key to service life: choose the lubricant recommended by the manufacturer and check alignment with the supports. Mounting must be done with suitable tools to avoid damaging the thread or the balls.

NSK FS series ball screws can be interchanged with other brands such as THK, HIWIN or Bosch Rexroth, provided diameter, lead, precision class and nut type match. In general, equivalents are established by these dimensional and functional characteristics. If you have a part number from another brand, we can help you find the equivalent NSK replacement. Interchangeability is not automatic: always verify tolerances and mounting.
