Aluminum GT2 Timing Pulley, 20 Tooth, 5mm Bore (2-Pack)

Description

The Aluminum GT2 Timing Pulley is an essential component for building or upgrading precise linear motion systems in 3D printers, CNC routers, and various robotics projects. This 20-tooth pulley is specifically designed for 6mm wide GT2 timing belts, providing smooth and accurate power transfer critical for high-resolution 3D printing and precise CNC machining.

Constructed from lightweight and robust aluminum alloy, these pulleys offer excellent durability and resistance to wear, outperforming plastic alternatives under demanding conditions. The 5mm bore ensures a snug fit on common NEMA 17 stepper motor shafts, and the included M4 grub screws allow for secure fastening, preventing slippage and maintaining synchronization. Utilizing these pulleys helps improve overall print quality and machine reliability by minimizing backlash and ensuring consistent belt tension.
