Gearboxes +

G22A Gearbox
The G22A is a 22mm planetary gearbox suitable for servo applications where DC Servo brush or BLDC motor technology is specified. The G22A integrates perfectly to the DC022C for a very compact gearmotor with torques up to 0.3 Nm.

Features:

Sintered metal gears for high torque capacity
Sintered metal output bearings

Optional:

Ball bearings for higher radial loads
