Ballscrews

Ballscrews, precision industrial screws, convert rotary motion to linear motion, offering high accuracy, reversibility, and efficiency.

Description

Ballscrews are common industrial machinery and precision machines, consisting of a screw spindle and nut integrated with balls and their return mechanism. They convert rotary motion to linear motion or torque to thrust, offering high accuracy, reversibility, and efficiency. Ballscrews offer advantages like high efficiency, reversibility, backlash elimination, high stiffness, and lead accuracy. They replace conventional screw sliding friction with rolling motion of balls.

7. Miscellaneous: Antenna leg actuator, valve operator, etc.

Types of Ballscrew

Rolled Ballscrew

Rolled thread ball screws are the most common type of ball screws used in the industry. The manufacturing process for these screws involves cold forming the screw and nut threads, resulting in a smoother surface finish and a higher lead accuracy. Rolled th read ball screws suit low to moderate-load applications and offer high efficiency
and fast speeds.. There are three types of Rolled Ball screw they as follows:
A) Single Start Rolled Ball Screw
B) Double Start Rolled Ball Screw
C) Fourth Start Rolled Ball Screw

Ground Ballscrew

Ground ball screws are manufactured using precision grinding methods rather than cold forming. The result is a more precise and accurate screw with a higher lead accuracy than rolled thread ball screws. Ground ball screws have higher load capacity and are available with preload for high-rigidity applications. They are more expensive than rolled thread ball screws but are a great option for high-end applications with stringent accuracy requirements
Ground Ballscrews are found three series as follows:
A) Single start Rolled and Ground BallScrew
B) Second Start Rolled and Ground BallScrew
C) Forth Start Rolled and Ground Ball Screw.
