The NSK SFD series ball screw is a linear transmission component that converts rotation into axial displacement with high efficiency and repeatability. It is used in machine tools, automation equipment and positioning systems where precision and rigidity are critical. MR Accesorios Industriales sells this line for the Argentine market, with technical advice to choose the right configuration for each application.

The SFD series designation is read in blocks: the letters identify the ball screw family, and the numbers that follow indicate nominal diameter and lead. For example, in SFD 2005-3 the 20 corresponds to the screw diameter and 05 to the lead, while the suffix -3 defines the number of ball circuits per nut. In SFD 2506-4, the 25 and 06 follow the same logic, and the -4 indicates four circuits. These codes let you select the combination of load capacity and speed required by each axis.

In Argentine industry, SFD ball screws are used in machining centers, grinding machines, coordinate measuring machines, laser cutting equipment and industrial automation systems. They also appear in laboratory devices and special machines where smooth, backlash-free linear motion is required. Their ability to withstand high axial loads while maintaining precision makes them suitable for demanding duty cycles.

To select an SFD ball screw, take into account the axial load, rotation speed, length between supports and type of lubrication. The nut seal keeps contaminants out and retains lubricant; in environments with chips or dust, it is best to choose seals with greater protection. Alignment between the screw and the linear guide is essential to avoid parasitic stresses. Assembly requires rigorous cleanliness and a controlled tightening torque on the supports.

Ball screws from different brands can be interchanged if diameter, lead, number of circuits and nut type match. Series from manufacturers such as THK, HIWIN or Bosch Rexroth have dimensional equivalents, but tolerances and preloads may vary. If you bring the code from another brand or an unidentified part, at MR we will tell you the compatible alternative or quote the exact size you need.

To move forward with your project, send us the full code of the SFD ball screw you are looking for on WhatsApp, or the main dimensions if you do not have it at hand. At MR Accesorios Industriales we will quote you promptly and advise you on the most suitable configuration for your application.
