LEAD SCREW Structure

LEAD SCREW

A LEAD SCREW is a power-transmission component that converts rotary motion into linear movement. It is typically used together with a nut, bearings, and a drive mechanism. Through the thread lead, it moves a platform or mechanism along a linear path, making it suitable for positioning, lifting, pushing, and travel adjustment applications.

Converts Rotary Motion into Linear Movement

When used with a matching nut, a LEAD SCREW converts the rotational motion of a motor or handwheel into stable linear movement.

Adjustable Lead and Travel Speed

Different movement speeds and linear advances can be achieved by adjusting thread pitch, lead, and the number of thread starts, allowing the design to match different equipment travel requirements.

Provides Load-Bearing and Positioning Functions

A LEAD SCREW is suitable for carrying axial loads and can be used in mechanisms for platform positioning, lifting, clamping, pushing, and linear adjustment.

Supports Custom End Machining

Stepped shaft sections, keyways, threaded ends, flats, and other end features can be customized according to bearing, coupling, and drive-system requirements.

Suitable for Various Mechanical Equipment

LEAD SCREWS are commonly used in automation equipment, lifting platforms, valves, jigs and fixtures, 3D printers, conveying systems, and various linear-motion mechanisms.
