What the GT2-6 Timing Belt Pulley 20T is for

The GT2-6 Timing Belt Pulley 20T (Inner Bore 8mm) is a high-precision aluminum pulley designed for GT2 timing belts in 6mm width. It is built to deliver smooth and accurate motion transfer in belt-driven systems such as 3D printers, CNC machines, and robotics.

The 20-tooth pulley design supports controlled, repeatable movement for applications where positioning accuracy and consistent motion matter. The 8mm inner bore fits matching shafts in compatible mechanical assemblies.

Key features of the 20T GT2 pulley

• Precise motion control: The 20-tooth design supports smooth, backlash-free movement for accurate positioning and dependable motion transfer.
• Aluminum construction: The pulley is made from high-quality aluminum to provide strength while keeping weight low in compact motion systems.
• Secure shaft grip: Dual set screws help maintain a firm connection to the motor shaft for more stable operation.
• Built for GT2 belt systems: The pulley is optimised for 6mm-wide GT2 timing belts used in high-accuracy belt-driven assemblies.

Where the GT2-6 timing belt pulley is used

This timing pulley is suited to motion systems that need reliable and repeatable belt-driven performance. Common applications include desktop 3D printers, CNC motion assemblies, and robotics mechanisms that run on GT2 6mm belts.

The combination of an 8mm bore, lightweight aluminum body, and dual set screws makes the pulley a practical fit for compact drive systems where stable operation and accurate motion transfer are required.
