G51A Gear
The G51A is an economical 51 mm offset spur gearbox suitable for lower torque applications. The wide range of sintered steel gears combinations especially complement brushed motors when speed reduction in required. The G51A is also available in high torque or wide faced gears for increased output loads.

Features:

Maximum Load torque up to 1.24 Nm in the standard model
Load increased to 2.12 Nm in the high torque and up to 3.53 in wide face versions
Standard bronze bearings

Optional:

Special lubrication for extreme conditions
Ball bearings for high radial loads
Delrin gears for noise reduction
