Ball Bearing Stage - Feeding Screw Design

A feed screw, also known as an adjusting screw, has a 60-degree thread angle and is designated by the letter M. Metric threads are available in coarse and fine versions, distinguished by their machining precision. Utilizing a helical principle, it achieves linear motion (forward or backward). Since one revolution of the screw equals the distance of one pitch, if one pitch equals 0.5mm, then one revolution of the feed screw means it advances or retracts 0.5mm. It is used for adjusting length, distance, or measurement.

Linear ball guide - feed screw drive, multi-directional precision stages include: XYZ axis precision stages, XY axis precision stages, and X axis precision stages. The track uses linear ball guide, and the Gothic arc groove is composed of double arc grooves on the upper and lower stage surfaces of the body. The steel ball moving in the single groove has a two-point contact structure, and the double arc grooves have a total of four contact points, thus forming a robust stage structure. It uses feed screw drive and is suitable for simple and precise movement.
