350mm Trapezoidal 4 Start Lead Screw 8mm Thread 2mm Pitch Lead Screw with Copper Nut Documentation

Component Name

350mm Trapezoidal 4 Start Lead Screw 8mm Thread 2mm Pitch Lead Screw with Copper Nut

Description

The 350mm Trapezoidal 4 Start Lead Screw 8mm Thread 2mm Pitch Lead Screw with Copper Nut is a type of linear actuator component used in various industrial and DIY applications. It is a crucial element in mechanisms that require linear motion, such as CNC machines, 3D printers, robotic arms, and other precision engineering systems.

Functionality

The lead screw's primary function is to convert rotary motion into linear motion. When connected to a motor or other rotary driving source, the lead screw rotates, causing the nut to move along the thread, thereby achieving linear motion. This mechanism enables precise positioning, smooth movement, and high repeatability, making it an essential component in various applications.

Key Features

Length: The lead screw has a total length of 350mm, providing a substantial range of linear motion.
Trapezoidal Thread: The lead screw features a trapezoidal thread, which offers a high level of accuracy and repeatability. The trapezoidal shape allows for smooth engagement and disengagement of the nut, reducing backlash and increasing overall system precision.
4 Start Thread: The lead screw has a 4-start thread, meaning that there are four parallel threads cut into the shaft. This design feature enables the nut to move at a faster rate than a single-start thread, making it suitable for applications that require rapid linear motion.
8mm Thread Diameter: The lead screw has an 8mm thread diameter, which provides a robust and stable connection with the copper nut.
2mm Pitch: The lead screw has a thread pitch of 2mm, which determines the distance traveled by the nut for one complete revolution of the lead screw. A smaller pitch results in finer resolution and more precise movement.
Copper Nut: The component comes with a copper nut, which provides a high level of wear resistance and reduced friction. The copper material also offers good thermal conductivity, making it suitable for applications where heat dissipation is a concern.
Material: The lead screw is made from high-quality steel or stainless steel, ensuring durability, corrosion resistance, and high strength-to-weight ratio.
Precision Engineering: The lead screw is precision-engineered to ensure high accuracy and repeatability, making it suitable for demanding applications where precision is critical.
