What this C-Beam extrusion is for

The C-Beam C-Channel V-Slot Extrusion (20 Series) – 40mm x 80mm x 2.5m (Black) is a high-strength aluminum profile built for heavy-duty linear motion and structural support. The C-shaped channel improves rigidity while supporting integrated motion systems that use V-slot wheels and lead screws.

This extrusion suits CNC machines, 3D printers, laser engravers, and industrial automation systems where strength, alignment, and modular assembly matter.

Key features and benefits

• 6063-T5 aluminum construction provides superior strength and durability for demanding mechanical builds.
• Anodized black finish adds corrosion resistance and a clean, professional appearance.
• 40mm x 80mm C-Beam design increases rigidity and load-bearing capacity for heavier-duty applications.
• Integrated V-Slot linear motion support allows use with V-Wheels, lead screws, and gantry plates for precision movement.
• Pre-drilled core with M5 tapping support helps simplify secure assembly and component mounting.
• Modular 20 Series platform works with matching T-nuts, brackets, and fasteners for flexible machine design.

Where a 40mm x 80mm C-Beam works best

CNC machines and router frames

The rigid C-Beam profile provides high structural stability for precision motion systems and frame assemblies.

Linear actuators and motion systems

This extrusion works with lead screws, belt drives, and V-slot wheels, making it suitable for controlled linear travel in custom equipment.

Automation, robotics, and machine enclosures

The modular format is well suited to heavy-duty machine frames, enclosures, and robotic assemblies that need both strength and configuration flexibility.

Why builders use this C-Beam profile

This C-Beam C-Channel V-Slot extrusion is a powerful, modular, and easy-to-use component for high-precision mechanical systems. It offers exceptional strength and versatility across a wide range of engineering and automation projects.
