SEW-Eurodrive has extended the MC Compact series of helical and helical-bevel gear units for mixer and agitator applications. The units have an extended bearing distance (EBD), providing customised gear units capable of absorbing the high bending moments and axial forces that occur in agitator applications.
The gear assemblies offer stronger bearings within the gear unit itself, to eliminate the need for separate bearings. The EBD systems consist of add-on components (such as stronger bearings), a larger diameter output shaft, and an extended bottom bearing housing. The additional housing effectively increases the distance between the top and bottom bearings, adding strength and rigidity to the total unit.
They are suitable for agitators, mixers, aerators, dry-cooling towers or thickeners. Because of the potential contamination of the agitated medium by bearing lubricants, SEW-Eurodrive can also incorporate a drywell sealing system to prevent oil leakage at the output shaft in vertical mounting positions.
Available in eight sizes, with a rated torque of 6kNmto 65kNm, the EBD MC Compact series industrial gear units can produce powers of 5kW to 250kW. The same bearing housing can be used for foot and flange mounted gear units, which provides a high degree of flexibility for specific applications.
