Gearbox housing with integrated carrier and sealing surfaces
-
Gears & toothing for the transmission of the motor speed
-
Bearings & bushings for axial and radial guidance
-
Seals & shaft seals for sealing against water and oil
-
Shifting and power transmission elements
-
Fastening parts, screws & spacer sleeves
Together, these assemblies ensure stable power transmission and minimal friction losses.
