VRB High Precision Planetary Gearbox

Quietly operation of VRB speed reducer thanks to the use of helical gears.

High precision positioning for backlash smaller than 3 arc.min.

High rigidity and high toque of 3F VRB precision gearbox due to the use of integrated roller bearing.

It is convenient to install our servo gearbox on any brand of motor with any size.

The use of high quality lubrication grease ensures free of maintenance and no grease leakage.
