## Summary description

Trapezoidal lead screw with 8 mm nominal diameter and 400 mm overall length, supplied as OEM part. Designed to convert rotary motion into linear motion in mechanical assemblies, CNC devices, linear actuators and positioning systems. Manufactured to standard trapezoidal thread profile for reliable axial load transmission and smooth travel. Suitable for repair, prototyping and custom machinery.

## Long description

Trapezoidal lead screw with 8 mm nominal diameter and 400 mm overall length, supplied as an OEM part. Engineered to convert rotary motion into precise linear movement, this shaft uses a standard trapezoidal thread profile to provide reliable axial load transmission and smooth travel. It is suitable for repair, prototyping and integration into custom machinery, CNC devices, linear actuators and positioning systems where a compact, robust lead screw is required.
Advantages
This trapezoidal lead screw offers consistent thread geometry and dimensional stability for repeatable linear motion. Its 8 mm nominal diameter balances compact size with sufficient rigidity for light to moderate axial loads. The 400 mm overall length provides extended travel or allowance for mounting and end fixtures. Being supplied as an OEM part ensures compatibility with industrial assemblies and replacements without unnecessary finishing or coatings.
Suitable for
Linear actuators and small positioning stages
CNC hobby machines and desktop milling/engraving systems
Repair and replacement of worn or damaged lead screws
Prototyping and custom mechanical assemblies
Key specifications
Nominal diameter: 8 mm
Overall length: 400 mm
Thread profile: standard trapezoidal
Function: converts rotary motion to linear motion
Intended use: OEM mechanical component for assemblies and repairs
How to use
Install the lead screw into the assembly by securing the ends in appropriate bearings or supports, ensuring axial alignment with mating nuts or sliding blocks. Apply the correct mating trapezoidal nut or carriage, and verify smooth travel along the full 400 mm length. For rotary drive, couple the screw to a motor or handwheel using a compatible coupling, taking care to prevent radial loads on the screw and maintain proper end support to avoid bending.
Usage recommendations
For reliable operation, use a matching trapezoidal nut sized for an 8 mm screw and keep thread engagement free of debris. Periodically inspect for wear and apply lubricant suited for lead screws to reduce friction and extend service life. When installing, support the screw ends to minimize deflection when used under axial load.
