The flange is located in the axial center of the housing. To simplify the Installation, very large access areas are provided inside the machine and on the bearings; it is an extraordinary advantage when assembling the machine and for maintenance.
This housing shape is a very suitable base for a wide range of stages of expansion. The EM type median flange is a functional, multi-purpose bearings – for durable machines, from low speeds to turbocharged generators that run at maximum velocity. Center flange mounted slide bearings, designed with an enlarged opened surface (ZM7, EM9S, EM14S/XS), are a special type of bearings for smaller shafts. In cases where products have a low degree of variation, these mounts offer features optimized for natural cooling operation, which means that, i.e. two-pole electric motor powered machines can be built without separate lubrication units.
