GT2 20T Timing Pulley 6.35mm Bore

The GT2 20T timing pulley with a 6.35mm bore is a precision mechanical component designed for smooth and accurate power transmission in motion control systems. Commonly used in 3D printers, CNC machines, laser engravers, and robotics projects, this pulley is optimized for GT2 timing belts to ensure minimal backlash and high positioning accuracy. Manufactured from durable aluminum alloy, the pulley offers excellent wear resistance and long service life while remaining lightweight. The 20-tooth design provides reliable torque transfer, making it ideal for stepper motor applications. It’s available in two belt width options, 6mm and 10mm, allowing you to match the pulley to your existing belt setup.

The precision-machined 6.35mm (1/4 inch) bore ensures a secure fit on motor shafts, typically fastened using grub screws. This pulley is suitable for both DIY projects and professional automation systems where consistent motion and accuracy are critical.
