Aluminum GT2 Timing Pulley 16 Tooth – 5mm Bore for 6mm Belt

The Aluminum GT2 Timing Pulley 16 Tooth – 5mm Bore for 6mm Belt is designed for precise motion control in 3D printing, CNC machines, and robotics. It is specifically engineered for use with 6mm wide GT2 timing belts and is not compatible with MXL belts due to the differing tooth profiles.

With 16 finely machined teeth and a 5mm inner bore, this pulley is ideal for direct coupling with NEMA 17 stepper motors. Its lightweight and durable aluminum construction ensures reliable performance under continuous load. The integrated dual M4 set screws provide a firm grip on the shaft, minimizing slippage and ensuring consistent torque transfer.
