Acme Threaded Rod

An ACME threaded rod, also known as an ACME screw thread, is a type of screw thread commonly used for linear motion applications, particularly in machinery and mechanical systems. It is designed to provide precise and smooth movement in applications such as lead screws, jackscrews, and linear actuators. ACME threads have a trapezoidal shape, which sets them apart from the more common V-shaped threads found in standard screws and bolts. The ACME thread profile typically has a 29-degree thread angle, which is close to the 30-degree angle of an isosceles trapezoid. This design provides a better balance between strength and ease of manufacturing than some other thread profiles. ACME threaded rods are used in various applications where linear motion and positioning need to be controlled precisely. Some of the key applications include: CNC (Computer Numerical Control) machinery: ACME threads are used in CNC machines to control the movement of the cutting tools or workpieces. Lift mechanisms: ACME threaded rods are commonly used in scissor lifts, car jacks, and other lifting devices to provide controlled vertical movement. Conveyor systems: ACME threads can be used to control the movement of conveyor belts and similar systems. 3D printers: ACME threaded rods are used to move the print head or the build platform with precision in 3D printing. Linear actuators: These are devices that convert rotary motion into linear motion, and ACME threaded rods are often used to provide this conversion. ACME threaded rods come in various sizes and materials, making it possible to choose the right one for a specific application. They are known for their high load-bearing capacity and low friction, making them suitable for situations where precise linear motion is required.
