Recirculating Ball Screw

We VXO are one of the top recirculating ball screw manufacturers in China. Our standard product lead time is 7-15 days, customized design product is 20-30 days. Our bearing ball screws are ideal for laboratory, semiconductor, and medical applications. The interface between the ball screw and the nut is made by balls that roll in matching ball forms. With rolling elements, the linear ball screw has a low friction coefficient. The forces transmitted are distributed over a large number of balls, giving a low relative load per ball comparatively.

Recirculating Ball Screw Types
The ball screw drive is an assembly that converts rotary motion to linear motion. Recirculating ball screw consists of a ball screw and a ball nut packaged as an assembly with recirculating balls. We have two types of VXO Precision Ball Screws, one of which is Standard Products in stock for short delivery of 7-15 days, and the other is Customized Products with flexible design delivery 20-30days.

Recirculating Ball Screw Application
Recirculating ball screws are used in aircraft and missiles to move control surfaces, especially for electric fly by wire, and in automobile power steering to translate rotary motion from an electric motor to axial motion of the steering rack. Linear rail ball screws are also used in machine tools, robots, and precision assembly equipment.

Recirculating Ball Screw Application
Recirculating Ball Screw Material
All recirculating ball screws are roll formed of quality high carbon or alloy steel. Screws are induction case hardened for maximum load and service life. Nuts are made from carburizing grades of carbon or alloy steel and case hardened for wear resistance. High grade, bearing quality chrome steel balls are utilized. Return circuitry is secured with alloy capscrews for maximum reliability.

Recirculating Ball Screw in CNC
In the CNC industry, the ball screw is mostly used in the CNC machine tool itself, and it is also the most important part of the CNC engraving machine and the high-gloss machine. Its role is related to the accuracy of the products produced. Its role is mainly to locate the place where the workbench needs precise positioning and transmission, which is often used in conjunction with servo motors. Recirculating ball screw in CNC include precision CNC machine tools, automation equipment, industrial robots, conveying machinery, medical equipment, aerospace industry and other industries

Advantages of Recirculating Ball Screw
Linear ball screws are more efficient, requiring less torque. Ball screws have lower friction and run at cooler temperatures. Linear ball screws require grease or oil lubrication to achieve design life. Ball screws need to be replaced less frequently.

Recirculating Ball Screw Mechanism
The internal recirculation type ballscrew, consists of the screw spindle, the ball nut, the steel balls and the ball return caps. The steel balls make only one revolution around the screw spindle. The circuit is closed by a ball return cap in the nut allowing the balls to cross over adjacent ball tracks. Since the ball return caps are located inside the nut body, this is called the internal recirculation type ballscrew.
