What the GT2-6 timing belt pulley does

The GT2-6 Timing Belt Pulley 20T (Inner Bore 5mm) is a high-precision aluminium pulley made for 6mm GT2 timing belts. The pulley is designed to deliver smooth and accurate motion transfer in belt-driven systems used for 3D printers, CNC machines, and robotics.

Key features of the 20T GT2 pulley

• 20-tooth pulley design supports smooth, backlash-free movement for precise motion control.
• High-quality aluminium construction provides durability while keeping weight low.
• Dual set screws help create a secure fit on the motor shaft.
• Optimised for 6mm GT2 timing belts to support high-accuracy motion transfer.

Why a 20T GT2 pulley is used in motion systems

A 20T GT2 pulley is commonly used where repeatable belt-driven movement matters. The combination of precise tooth engagement, lightweight aluminium construction, and secure shaft mounting makes the pulley suitable for machines that rely on consistent positioning.

Use cases for 3D printers, CNC machines, and robotics

• 3D printers: Suitable for axis motion systems that use GT2 belts for smooth travel and accurate positioning.
• CNC machines: Useful in compact belt-driven mechanisms where dependable motion transfer is required.
• Robotics: Works in custom motion assemblies that need a lightweight pulley with a firm shaft grip.
