GT2 / 2GT Timing Pulley with D Bore – Aluminum Synchronous Pulley, 20T–28T, for 3D Printers & Motion Systems
Product Description
The D Hole GT2 / 2GT Timing Pulley is a precision aluminum synchronous pulley designed for use in timing and motion systems such as 3D printers, CNC machines, and other mechanical automation applications.
This pulley features a D-shaped bore, which provides better torque transmission compared to standard round bore designs with set screws. Thanks to this construction, the pulley is more resistant to slipping and ensures a more stable connection between the shaft and the pulley.
The pulley is manufactured from aluminum alloy, offering a good balance between low weight and mechanical strength. The flange is made of galvanized iron, which helps maintain belt alignment during operation.
With a 2 mm tooth pitch (GT2 / 2GT) and multiple tooth count options, this timing pulley is suitable for precise positioning and smooth motion control.
