Extended bearing distance gearboxes

SEW-Eurodrive has introduced a family of locally assembled gear units. Featuring an extended bearing distance (EBD), the EBD MC Compact series helical and helical-bevel gear units have been engineered to absorb the high bending moments and axial forces that occur in mixer and agitator applications. The EBD MC Compact range is fully assembled in Australia, ensuring SEW-Eurodrive can provide fast turnaround on complete gear-unit packages.

Traditional mixing and agitation solutions depend on separate bearings for the agitator shaft in order to absorb axial and radial forces that occur during the agitation process. The EBD MC Compact gear unit assemblies eliminate the need for separate bearings by incorporating an additional bearing housing onto the existing standard bearing housing. This increases the distance between the upper and lower bearings by approximately 50%, adding significant rigidity to the mixer shaft and minimising the axial and radial loads transferred to the gears and bearings.

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.

The EBD MC Compact series is available in various mounting arrangements and configuration options, and offered in five sizes, with torque ratings of 16 to 48 kNm, suitable for motor powers up to 250 kW.
