Regardless whether you want your servo gear unit to be a dynamic all-rounder, to offer high efficiency or have an increased overload capacity – with our planetary servo gear unit of the new PxG family you are always making the right choice. The series is available in six sizes with gear ratios of 3 to 1000. These cover a torque range of 20 to 6500 Nm and the rotational clearance is well under one angular minute.

The PxG planetary servo gear units ensure performance and quality through innovative components and the latest processing methods. As well as continuous calculation, assembly and testing options. In terms of delivery times and service of the new modular gear unit system, you can expect the reliability SEW‑EURODRIVE is known for.
