Screw rail
NB
The NB Slide Screw is a unique drive unit which makes efficient use of friction to convert rotary motion to linear motion. This unit is a very simple mechanism containing only radial bearings in contact with a shaft, providing ease of maintenance. Even if an accident occurs, this unit slips on the shaft, stopping itself to prevent further damage. The unit is applicable to a wide variety of devices by fully utilizing its features, although while accurate positioning would require an extra control.
