Detailed information
-
The NB slide screw consists of two aluminum blocks, each equipped with three bearings set at a specific angle to match the lead on both end faces. A round shaft is inserted between the two blocks, and by rotating the shaft, linear motion is achieved according to the contact angle between the shaft and the outer ring of the bearings. Additionally, the load can be adjusted using hexagon socket bolts that incorporate springs.

Linear drive is possible with a round shaft; it can be used without lubrication. ■ Linear drive is possible with a round shaft The NB slide screw uses a round shaft, allowing it to easily accommodate long strokes. ■ It can be used without lubrication The bearings on both sides are filled with grease, so there is no need for lubrication unless there are issues such as corrosion of the drive shaft.
-
High mechanical efficiency and overload prevention mechanism ■ High mechanical efficiency The slide screw utilizes a mechanism that takes advantage of the rolling motion of bearings on both sides and the drive shaft, resulting in a high mechanical efficiency of 90%. ■ Overload prevention mechanism In the event of an abnormal overload, it will stop due to slipping, thereby preventing accidents before they occur.
