Precision Engineering for Linear Motion and Structural Frames

Engineered for high-precision linear motion and robust structural framing, the 2040 V-Slot Aluminum Extrusion is the foundational building block for custom 3D printers, CNC routers, laser cutters, and robotic chassis. Featuring a dual-slot configuration on its wider face, this profile provides significantly higher torsional rigidity and load-bearing capacity than standard 2020 profiles, making it ideal for axes that undergo constant mechanical stress.

Unlike traditional T-slot extrusions, the specialized V-shaped grooves on all four sides allow compatible V-wheels and linear bearings to ride smoothly and directly along the track. This dual-purpose design means your structural frame elements double as precise linear guide rails, saving space, weight, and assembly time.

Dimensional Specifications

Every extrusion is manufactured to tight tolerances to ensure seamless compatibility with standard metric hardware and modular brackets:

• Profile Dimensions: 20mm x 40mm
• Center-to-Center Slot Distance: 20mm
• Center Bore Diameter: Ø4.2mm (optimized for M5 thread tapping)
• Outer Slot Opening: 6.2mm
• Inner Slot Width: 11.0mm
• Wall Thickness: 1.8mm
• V-Groove Depth: 4.3mm
• Finish: Matte Black Anodized

Modular Versatility

Whether you are building an automated test fixture, a custom camera slider, or upgrading a 3D printer frame, the 2040 V-Slot profile integrates easily with standard M5 T-nuts, drop-in nuts, and modular corner brackets. The Ø4.2mm dual center bores can be easily tapped to create secure, flush end-to-end connections.
