Electric actuator manufacturer AUMA, which is based in Pennsylvania, USA, has launched the new GQB compact gearbox range. In addition, all housing parts are powder-coated using AUMA’s corrosion-resistant two-layer powder coating system.
The housing incorporates a coaxial primary reduction gear as well as integral mounting flanges for the actuator, hand wheel and valve. This aims to reduce the number of parts and the amount of material required, without compromising performance.
The new gearboxes are currently available in three sizes – GQB 160.1, GQB 200.1 and GQB 250.1 – covering a torque range from 21 000 Nm to 84 000 Nm. The gearboxes can be used either in combination with an AUMA SA multi-turn actuator or with a hand wheel for manual operation.
