Low-backlash gearboxes GX Series

A complement of the NX series Characterised by a low backlash, GX gearboxes are ideal for applications needing high torque and optimum motion quality. In combination with NX servomotors, they offer a compact motor-gearbox solution optimised to provide the best dynamic performances. GL gearboxes are an economical alternative perfectly adapted to usual applications where a low backlash is not requested. They are associated to NX servomotors of size 1 to 3.

GX gearboxes
High performance gearboxes Speed ratio : • 1 stage : 3, 4, 5, 6, 7, 8, 9 and 10 ratio • 2 stages : 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90 and 100 ratio Low backlash, smooth and quiet functioning High stiffness Life-lubricated Up to IP65 protection
