Buy this pulley for maximum torque.
The pulley is made from hardened steel, this 15 teeth HTD5 motor pulley is the perfect match for any motor with an 8mm drive shaft.
The pulley comes with 1x M4 hex grub screw, 3x3x18mm keyway piece & Hex tool
Fitment: If your motor shaft doesnt have a key way slot simply grind a flat spot onto the side of the shaft, deep enough (1.5mm) for the key to fit when the pulley is installed. You must also use thread locker on the grub screw & I also put threadlocker onto the motor shaft/inside the pulley, this locks the motor pulley onto the motor shaft very well.
MORE TEETH = HIGHER TOP SPEED
LESS TEETH = MORE TORQUE
