ball screw

he left and right rolling bead screw is a high-precision transmission component mainly used to convert rotational motion into linear motion, or vice versa. It achieves efficient and low friction transmission through the rolling contact of balls between the screw and nut, and is widely used in fields such as CNC machine tools, automation equipment, robots, etc.

1、 Working principle
When the screw rotates, the nut will be converted into linear motion according to the lead distance with the rotation angle of the screw. The passive workpiece is connected to the nut seat and nut to achieve linear motion.

2、 Main features
High transmission efficiency: with minimal friction loss, the transmission efficiency can reach over 90%.
High precision: The highest precision can reach C0 level.
High speed feed and micro feed may have extremely low starting torque, enabling precise micro feed.
High axial stiffness: By preloading, thread clearance can be eliminated, improving contact stiffness and transmission accuracy.
Non self-locking, reversible transmission: can be converted from rotational motion to linear motion, or from linear motion to rotational motion.
3、 Application Fields
Industrial automation: such as robot joint drive, automated assembly line, etc.
Precision machining equipment: such as CNC machine tools, precision tool machines, etc.
Electronic machinery: such as measuring instruments, medical equipment, etc.
Conveyor machinery: such as material handling equipment, nuclear reactors, etc.
Aviation components: such as aircraft flaps, airport load equipment, etc.

4、 Advantages of left and right rolling bead screw
Positive and negative rotation integrated molding: saves clamping steps and reduces space.
High transmission accuracy: The transmission accuracy reaches 0.01 millimeters.
High speed operation without lagging: suitable for machine tools and automation equipment.
No need for additional structural transformation: make bidirectional walking more efficient.
