2040 Belt Tensioner Mildsteel Mechanism for 3D Printer

2040 Belt Tensioner Mildsteel Mechanism for 3D Printer

• 2040 Belt Tensioner Mechanism is a rigid mild steel tensioning unit designed to maintain accurate belt tension on 3D printer frames.
• Compatible with 2040 aluminium extrusion profiles, making it easy to integrate into common extrusion-based builds.
• Helps reduce belt slip, backlash, and vibration by keeping the belt correctly tensioned.
• Also available as a 2020 belt tensioner option for 2020 aluminium profile systems.

Specifications
