SEW-EURODRIVE has introduced the PxG economy series, expanding its PxG planetary servo gear unit portfolio. The component provider added three performance classes for machine builders and OEMs seeking cost-effective servo performance for standard industrial automation applications.

The new P1.G, P2.G and P3.G gear units extend the existing PxG family below the P5.G, P6.G and P7.G precision range. SEW-EURODRIVE said its expanded portfolio allows customers to match gear unit performance more closely to application requirements rather than specifying higher levels of precision, torque capacity, or load capability than the machine requires.

“Every automation application has different performance requirements,” said Anecia Hoffield, servo product manager at SEW-EURODRIVE. “The PxG economy series gives machine builders more flexibility to select the performance their machines actually need while maintaining the quality, engineering support and long-term reliability they expect from SEW-EURODRIVE.”

Founded in 1931, SEW-EURODRIVE is an industrial automation leader. It has operations in more than 50 countries, 17 manufacturing plants, 92 assembly facilities, and over 21,000 employees. The Bruchsal, German-based company provides engineered systems for industries including automotive, food and beverage, pharmaceuticals, mining, steel, logistics, energy, and more.

SEW-EURODRIVE said it designed the PxG economy series for applications with low to medium technical requirements. Typical uses include packaging equipment, assembly machinery, material handling systems, carton erectors, gantry robots, and machine tool portals.

Each performance class addresses a different level of mechanical demand. P1.G is intended for standard applications with relatively low overhung loads. P2.G provides additional load capacity for applications with increased radial forces. P3.G combines cost-optimized straight gearing with higher-capacity bearings for applications requiring greater mechanical strength while remaining within project budget constraints.

The PxG economy series is available in five sizes with peak torque ratings from 11 to 500 Nm. The gear units are offered in one- and two-stage configurations, provide rotational clearance from 6 to 12 arcminutes, and have a rated service life of more than 20,000 hours.

The modular system includes solid-shaft designs with smooth, keyed, or splined output options, depending on the performance class. Food -grade lubrication options and multiple mounting interfaces support use across a range of machine designs.
