SEW-EURODRIVE PxG Economy Series Broadens Servo Gear Choices

Industry Update

Design World reported on August 13, 2026 that SEW-EURODRIVE has expanded its PxG planetary servo gear unit portfolio with a new economy series for standard industrial automation applications. The new P1.G, P2.G and P3.G classes extend the PxG family below the P5.G, P6.G and P7.G precision range.

The update is positioned around application-based selection. P1.G is described for standard applications with lower overhung loads, P2.G adds load capacity for higher radial forces and P3.G combines straight gearing with higher-capacity bearings for applications that need more mechanical strength while still controlling project cost.

The reported range covers five sizes, one- and two-stage configurations, peak torque ratings from 11 to 500 Nm, rotational clearance from 6 to 12 arcminutes and a rated service life of more than 20,000 hours. The modular platform includes solid-shaft designs with smooth, keyed or splined output options depending on the performance class.

Design World also noted food-grade lubrication options, multiple mounting interfaces and integration with SEW-EURODRIVE engineering tools including SEW-Workbench, DriveCAD and DriveConfigurator.

Buyer Considerations

For machine builders and OEM sourcing teams, the practical point is specification fit. A broader planetary servo gear unit range can reduce the need to select a higher precision or higher load-capacity gearbox when a standard automation axis does not require it.

Buyers comparing gear motors, servo gearboxes and automation drives should map the new classes against radial load, overhung load, torque, clearance, mounting interface, shaft style and lubrication requirements. The reported food-grade lubrication option may be relevant for packaging or handling lines where hygiene rules affect component selection.

The update may also simplify platform planning when one machine family needs both economy and precision gear unit options. Engineering teams should still confirm final sizing, duty cycle, bearing loads, motor adapter compatibility and service-life assumptions against the original manufacturer tools and documentation before changing a bill of materials.

Frequently Asked Questions
