NSK produces the largest number of ball screws in the world at the moment. Controlling friction is a principal motivation and, this firm produces a large selection of ball screws, covering the vast majority of requirements. NSK Ball Screws are made to any dimensions, whether it is very tiny or very large. You can buy an NSK Ball Screw for just about any situation, such as mechanisms that make LCDs and semiconductors, together with machine tools and general machinery.

NSK Ball Screws are available in many preconfigured types. A primary option is the BSS Series, which is described as high-speed and low-noise. These are minimalistic ball screws which are manufactured to meet specifications that need the ball screw assembly to move quickly, where low friction is essential. Another option of NSK Ball Screw is the TW Series that is manufactured to work in Twin-Drive Systems. There is also the HTF-SRC Series NSK Ball Screws, which are strong enough to take high loads and fast speeds. These produce low levels of noise as another feature. Further variations of NSK Ball Screws include assemblies that are especially resistant to dust (the V1 Series), along with systems specifically created to be used with the Mold Clamping Systems in Injection Molding Machinery. This design of NSK Ball Screw is produced as the HTF-SRD Series, and incorporates a new means of keeping the ball bearings in circulation. This permits the ball screw assembly to function at a higher speed and with a large load. Other NSK Ball Screws work best in a vacuum, incorporating a thin film lubrication technology.
