The NSK VSS series ball screw is engineered for applications that demand accurate linear positioning and dependable repeatability. It is a common choice in machine tools, automation systems, and other equipment where rotational motion must be converted into smooth axial travel. MR supplies this series to industrial customers across the United States, Canada, Mexico, and South America, with technical support to help identify the right configuration.
Understanding the VSS code helps when ordering. The prefix identifies the ball screw family, while the following digits state the nominal diameter and lead. A suffix such as -6E, -5E, or -4E indicates the number of ball circuits or effective turns in the nut. For example, VSS3210-6E and VSS5050-4E represent different diameter and lead pairings. Using the full code ensures you receive the exact screw your equipment requires.
Typical installations include machining centers, milling machines, grinders, coordinate measuring systems, Cartesian robots, and high-precision positioning stages. The VSS series also appears in laser cutting machines, industrial 3D printers, and manipulators. Low friction losses make these screws suitable for fast cycles and moderate loads, provided they are mounted and lubricated correctly.
Selection should account for axial load, rotation speed, required precision, and operating environment. The VSS series generally includes sealing and recirculation features that influence axial play and rigidity. Proper mounting involves aligning the supports, applying the specified preload, and using compatible grease or oil. Keeping the screw clean and protected from chips or dust helps preserve its service life.
When replacing a ball screw from another manufacturer, verify that diameter, lead, length, nut type, and precision match. A similar code alone is not enough; the mounting interface and load capacity must be checked. If you have a code from another brand or an unidentified part, send the details and MR can suggest a compatible alternative or the correct replacement.

Frequently asked questions
- What does the -6E or -5E suffix mean on VSS ball screws?
- The number before the E indicates the number of turns or ball circuits in the nut. A higher number generally means greater load capacity and rigidity, though the nut size may also change. The complete code defines the ball screw.
- How do I request a quote for a VSS ball screw?
- Send the exact code (for example, VSS3210-6E) or your machine data—diameter, lead, length, and precision—via WhatsApp or email. MR will respond promptly with a quotation.
- Can I replace a ball screw from another brand with an NSK VSS one?
- Yes, if the mounting dimensions, diameter, lead, length, and precision match. Provide the original part code and MR will indicate the equivalence or a compatible alternative.
