For linear motion that needs to be precise and efficient, the NSK FS series ball screw turns rotational input into axial movement. It fits machine tools, automation systems and positioning applications where rigidity and repeatability matter. MR supplies this line to customers across the United States, Canada, Mexico and South America.

Reading the FS code helps you order the right screw. Take W1001FS-1-C3T4: the 10 is nominal diameter in mm, 1 is lead, the single nut is shown by -1, and C3 is the precision class. The T4 ending covers return or preload style. In W1202FS-2-C5T10, 12 means diameter, 02 means lead, the -2 indicates a double nut, and C5 is the precision grade. With these details you can match the screw to your machine.

These ball screws are common in machining centers, CNC lathes, grinders, coordinate measuring machines, laser cutting tables and factory automation. They also appear in food, pharmaceutical and automotive plants where motion must be smooth and require little maintenance. MR provides them as spare parts for production facilities and workshops.

When choosing a model, look at axial load, speed, accuracy and how the screw will be mounted. The FS series comes in precision classes from C3 to C5 and with different nut designs for preload. Sealing and lubrication affect how long the screw lasts, so use the lubricant specified by the manufacturer and confirm alignment with the end supports. Install with the correct tools to protect the thread and balls.

NSK FS ball screws can replace units from other makers such as THK, HIWIN or Bosch Rexroth when diameter, lead, precision class and nut type are the same. Equivalents are usually based on those dimensional and functional data. If you have a part number from another brand, MR can help you locate the NSK equivalent. Always check tolerances and mounting before substituting.
