In-Line Precision Planetary Servo Gearboxes Available from Heason

ZF Industrial's Servoplan® PG precision grade planetary gearboxes are available in the UK from Heason Technology Limited. Aimed at demanding servomotor drive applications, with ratios between 3:1 and 100:1 and output torques from 25 to 3000 Nm, the low backlash German manufactured range is fully interchangeable with other major brand servo gearboxes. The modular design allows a wide choice of mounting and output shaft configurations as well as assembly to almost all brushed and brushless servomotors - including Heason's own AKM series from Danaher.

The PG range is available in six single-stage sizes for a reduction ratio to 10:1 and five dual-stage designs for up 100:1 ratio. The high efficiency design uses taper roller bearings and an optimised gear tooth form for highest torque combined with low noise and low heat dissipation. The impressive backlash specification can be less than 2 arc minutes under optimal conditions. A typical service life of 20,000 + hours is quoted with minimal maintenance thanks to the PG's IP65 sealed and lubricated-for-life housing.

For less demanding applications and where price/performance needs to be optimised for OEM applications, Heason can also supply the ZF-PGE range which has a similar sealed housing construction but utilises a precision ball-bearing system providing up to 670 Nm torque capacity with ratios to 100:1. The PGE range can suit servo and fractional horsepower motors.
