The NSK SRC series ball screw turns rotary input into axial movement along a linear axis. Machine tools, automation cells and positioning systems rely on it where accuracy and stiffness matter. MR Industrial Accessories LLC supplies this line across the United States, Canada, Mexico and South America, and assists with selection.
The PFRC code tells you most of what you need. Take PFRC 2812-3.5: the first figures give a 28 mm diameter and a 12 mm lead, and the number after the hyphen is precision grade 3.5. In PFRC 4010-5, the screw measures 40 mm in diameter with a 10 mm lead and grade 5. Reading the code this way lets you match the screw to the load and speed your axis demands.
Typical installations include machining centers, grinding machines, Cartesian robots, precision presses and measuring equipment, as well as laser cutting machines, industrial 3D printers and material handling systems. Because the design carries high axial loads while running with low friction, it suits intensive duty cycles and repeated positioning.
Selection starts with axial load, rotation speed, critical length and mounting type. The SRC series offers various nut and preload configurations so you can tune rigidity. During installation, align the supports with the travel axis and confirm that lubrication is correct, whether grease or oil fits the application. Bellows or wipers that keep contaminants out help service life in areas with chips or dust.
Interchange with other brands is possible when diameter, lead, precision and nut type line up. Manufacturers such as THK, HIWIN or Bosch Rexroth set their own tolerances and load capacities, so check mounting dimensions and service conditions before substituting. Send the original part code and we will point you to the NSK equivalent.

Frequently asked questions
- What does the PFRC designation mean in NSK SRC series ball screws?
- PFRC is the prefix identifying the NSK ball screw series. The numbers that follow give nominal diameter and lead in millimeters, and the suffix after the hyphen shows the precision grade. For example, PFRC 4010-5 is a screw with 40 mm diameter, 10 mm lead and precision grade 5.
- How do I choose the right ball screw for my machine?
- Consider axial load, operating speed, length between supports and mounting type. The SRC series provides nut and preload variants to adjust rigidity. With those details, we help you select the PFRC code that fits your application.
- Can I replace a ball screw from another brand with an NSK SRC series one?
- Yes, if diameter, lead, precision and nut type match. Mounting dimensions and load capacities can differ between manufacturers, so verify compatibility. Send us the original part code and we will identify the corresponding NSK equivalent.
