Connection on the output end

– perfectly tuned to your application


PxG®planetary servo gear units offer the perfect connection on the output end for every requirement – be it solid shaft without key(N) or with key (K), splining shaft to DIN5480 (V) or with flange block shaft (B / C).

Rotational clearance

– lower rotational clearance for greater precision


PxG® planetary servo gear units have low rotational clearance as standard, meaning they are extremely precise even in their standard design. This high level of precision can be raised further through the option of reducing the rotational clearance.

Lubricant

– increase the service life of your gear unit


Our PxG® planetary servo gear units are fitted with a synthetic oil from our "GearOil by SEW-EURODRIVE" portfolio. Optionally, and depending on the application, they are also available with other lubricants.

Customized design

– when your application has special requirements


It goes without saying that it is also possible to custom design your PxG® planetary servo gear unit on request. We indicate such cases with an "X" in the type code.

Adapter on the input end (motor)

– for a smooth motor shaft


Depending on the servomotor used, various clamp couplings are available for the input end. For example, a bellows coupling can be used to compensate for a heat-related change in the length of the motor shaft (HB). The clamping ring optimized for the mass moment of inertia can be used specifically for dynamic applications (HL).
