## Summary description

Trapezoidal lead screw (OEM) with 8 mm nominal diameter and 330 mm overall length. Designed for linear motion and mechanical transmission in actuators, CNC machines, 3D printers and positioning systems. Machined for standardized thread profile to provide axial motion, compatibility with matching trapezoidal nuts and typical mounting in industrial and hobby applications.

## Long description

Trapezoidal lead screw with an 8 mm nominal diameter and 330 mm overall length, intended for linear motion and power transmission in machines and mechanisms. The screw is machined to a standardized trapezoidal thread profile to ensure reliable axial movement when used with compatible trapezoidal nuts. Its dimensions suit common installations in small actuators, positioning stages, CNC hobby machines and 3D printer assemblies where a compact, rigid lead element is required.
Advantages
This trapezoidal lead screw offers a standardized thread profile for predictable compatibility with mating nuts and carriage assemblies. Its 8 mm diameter provides a balance of rigidity and compactness for light- to medium-duty applications. The 330 mm overall length gives flexibility for retrofit or custom builds without the need for extensive cutting or modification. Machined surfaces and consistent thread geometry reduce backlash and wear when paired with appropriate nut materials and lubrication.
Suitable for
Linear actuators and single-axis positioning systems
Hobby and desktop CNC machines
3D printers and printer bed or carriage drives
Prototyping and DIY mechanical projects requiring axial motion
Key specifications
Nominal diameter: 8 mm
Overall length: 330 mm
Thread form: trapezoidal profile (standardized)
Application: linear motion and mechanical transmission
Material: machined metal (suitable for use with matching nuts and lubricants)
How to use
Install the lead screw concentrically with bearings or supports at both ends to maintain alignment and reduce deflection. Match the screw with a compatible trapezoidal nut of the correct internal profile and material; secure the nut to the carriage or moving element according to your assembly design. Ensure proper axial clearance and preloading where minimal backlash is required. Apply suitable lubricant along the thread to reduce friction and wear, and periodically inspect mounting points for looseness or misalignment.
Usage recommendations
For best performance, pair the screw with a nut made from a compatible material—bronze, polymer composite, or anti-backlash assemblies depending on required precision and load. Use end bearings to support radial loads and consider coupling the screw to a motor via a flexible shaft coupling to accommodate minor misalignment.
