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

The VSS series designation is read in blocks: the letters identify the ball screw family, and the numbers that follow indicate nominal diameter and lead, while the suffix with a hyphen and number (for example, -6E, -5E, -4E) refers to the number of ball circuits or effective turns. Thus, a VSS3210-6E has a specific diameter and lead, and a VSS5050-4E corresponds to another combination. These codes let you order the exact screw your machine needs.

In Argentine industry, VSS ball screws are used in machining centers, milling machines, grinding machines, coordinate measuring equipment, Cartesian robots and high-accuracy positioning systems. They also appear in laser cutting machines, industrial 3D printing and manipulators. Their ability to work with low friction losses makes them suitable for fast cycles and moderate loads, provided mounting and lubrication conditions are respected.

To select the right ball screw, take into account axial load, rotation speed, required precision and the environment. The VSS series usually incorporates sealing and recirculation circuits that define axial play and rigidity. Mounting requires carefully aligning the supports, applying the specified preload and lubricating with compatible grease or oil. Keeping the screw clean and protecting it from chips or dust are key to maintaining service life.

NSK ball screws can be interchanged with those from other manufacturers if diameter, lead, length, nut type and precision match. A similar code is not enough: the mounting interface and load capacity must be verified. If you have a code from another brand or an unidentified part, send us the data and we will indicate the compatible alternative or the right replacement.
