Tamiya 72004 Worm Gearbox Kit


Vendor's Description: 

The primary feature of this high-efficiency gear box is a worm gear, which locks the output shaft whenever the motor is not turning. The high gear ratios of 216:1 or 336:1 make this gearbox appropriate for small walking robots, lifting mechanisms, and other applications where high torque is desired.
