NSK ball screw circulation structure
A unit that rotates like a ball between a screw shaft and a nut is a ball screw. Since the balls require infinite circulation, the minimum required four components are the circulating parts in addition to the screw shaft, nut, and ball.

NSK ball screw advantages

1. High precision that is difficult to emulate

By using the grinding method and measuring instrument developed by NSK, an unparalleled level of accuracy has been achieved.

2. Excellent durability

By using high purity alloy steel, the product has excellent durability.

3.No backlash, high rigidity

Because the NSK ball screw uses a Gothic groove shape, the gap between the ball and groove can be minimized. And the gap can be made zero by applying a preload.

That is, there is no backlash. In addition, by managing the preload amount, rigidity that satisfies the conditions of use can be obtained. Even when no preload is applied,

The backlash becomes extremely small, so the backlash is small.

4. High efficiency obtained with smooth operation

If it is an arc groove, sometimes the ball is inserted into the groove of the nut and the screw shaft like a wedge. However, the Gothic groove does not have a similar phenomenon. In addition, the inherent low friction of the ball screw Thereby, smooth running and high-efficiency motion conversion can be obtained.

5.Various types of peripheral devices

NSK will provide high-quality ball screw support units (light load, small equipment, and large load, machine tools) as standard stock products, fully utilizing its technology in the slider field. In addition, as an accessory, NSK can also provide a lock nut with a guaranteed quality for locking the slider, an overrun limiter, and a hollow ball screw cooling unit.

6. Reasonable price

For standard ball screws, cost reductions are achieved through mass production planning. Even if the products are ordered, with the world's first production volume as the background, the centralized production of similar products is used to suppress the rise in prices.
