8/12/16mm Lead Screw Ball Screw

Lead screws and ball screws both convert rotary motion into linear motion.

They consist of a screw (threaded rod) and a ball nut, which contains recirculating balls that move along the screw's thread.

As the screw rotates, the ball nut moves along the screw, translating rotary motion into linear motion.

Accuracy of installation position of ball screw

(1) Measure the circumferential deviation value in the radial direction 

of the support part of the screw rod relative to the axis A of the threaded groove surface.

(2) Measure the coaxiality of the installation position of the part relative to the axis F of the screw support position.

(3) Measure the squareness of the end face of the supporting part relative to the axis E of the screw shaft support part

(4) Measure the rightness of the reference surface of the nut or the mounting surface of the flange relative to the axis G of the screw.

(5) Measure the coaxiality of the outer circumference (cylindrical) of the nut relative to the screw axis A.

(6) The parallelism of the outer edge (flat head mounting surface) of the indefinite nut relative to the axis C of the screw rod.

The ball screw is an ideal product for converting rotary motion into linear motion or linear motion into rotary motion.

Ball screw is the most commonly used transmission element in tool and precision machinery.

Its main function is to convert rotary motion into linear motion, or to convert torque into axial repetitive force.

It has the characteristics of high precision, reversibility and high efficiency. 

Due to its low friction resistance, 

ball screws are widely used in various industrial equipment and precision instruments.
