Special helical bevel geared motor

Special helical bevel gear unit

Helical bevel geared motors KKA 136. for billet mills

All inner parts are taken from the MAS program. The casing was designed according to an individual customer request in ductile iron EN-GJS-400-15 (GGG 40). The direct attachment of the roller conveyor motor results in very compact design.
