Planetary Gearboxes mount to all common servomotors.
June 16, 2003 - ZF-Servoplan PG 2-stage gearboxes offer low backlash of <2 arc-min for applications requiring exact positioning. They feature large-dimensional taper roller bearings; precision-ground, hardened gears; and Viton seals for IP-65 rating. ZF-Servoplan PGE Gearboxes, for less demanding applications, range from 5–670 Nm with ratios from 3–1000. They include input pilot for proper motor/gearbox alignment, integrated length compensation system, and cageless needle bearings.

ZF Industrial Drives Announces Line Extension For its ZF-Servoplan Planetary Gearboxes
Vernon Hills, IL - ZF Industries' Industrial Drives Group has released two product additions to augment its highly successful ZF-Servoplan Planetary Gearbox line: a 2-Stage Version of the industry-leading precision line (PG), and a new complete Economy Line of gearboxes (PGE). Known for their high efficiency, low running temperatures and low noise, ZF-Servoplan gearboxes can be used in any installation position and easily mount to all common servomotors due to a modular adapter flange system.
ZF-Servoplan PG gearboxes offer very low backlash (available < 2 arcmin) for demanding applications where exact positioning is critical. The PG features:
• A robust output shaft shoulder and large-dimensional taper roller bearings in their patented CC arrangement, allowing the highest possible axial and radial loads.
• Precision-ground, hardened gears with optimized gear tooth shape, ensuring the highest level of positional accuracy with low running noise.
• The highest-quality Viton seals designed with the smallest possible diameters, making the gearbox sealed per IP-65 and maintenance-free for life with minimal power loss and low running temperatures.
ZF-Servoplan PGE gearboxes were designed for less demanding applications where overall value is the primary concern. With its compact design and high power density, the PGE features:
• A wide range of available sizes (5-670 Nm) and ratios (3-1000), making the PGE extremely versatile and able to satisfy almost any application.
• An input pilot to ensure proper motor/gearbox alignment, and an integrated length compensation system to absorb thermal growth of the motor shaft that dramatically increases the life of the gearbox and the servomotor.
• Gearing with optimized geometries featuring cageless needle bearings in the planetary gears, ensuring high efficiency, high torsional rigidity and high acceleration torques with low levels of running noise.
