GB4 is a Reduction Gearbox for Electric Motors with 5Nm Gear Torque. It can combined with various types of motors. It contains heavily loaded steel gear wheels. The spur gears rotate on fixed steel spindles which are hardened and polished to a mirror finish. The thick output shaft rotates in robust sintered bushings. It can also be mounted on a ball bearing which can be provided in the output bush of the gearbox.

All the gears are housed between two metal plates with a plastic frame. All bearings are permanently lubricated and therefore require no maintenance. Economical versions with poly-acetal or sintered gears are available. This gearbox can also be combined with small to medium sizes of DC motors. This gearbox can combined with Synchronous Motors, BLDC Motors, PM Stepper Motors, and DC Geared Motors as per requirement.
