DM Series – Helical Gearmotors

DM Series – Helical Gearmotors

DM series, monoblock helical gearmotors are available with foot or flange mounted designs.  Upon request, they can be manufactured with motor adapters for standard IEC motors with B5 flanges. The standard motors are in compliance with IEC standarts with IE2 or IE3 efficiency class. DM series gearboxes are produced in nine different sizes and offer easy mounting and flexible connection options.

Thanks to their rigid structure, they are suitable to operate safely even in harshest conditions. Housing material is GG20 or GGG40 cast iron. Gears are produced from high quality, case hardened steel. Heat treatment process is applied to obtain 58-60 HRC surface hardness. The gears are precision ground to ensure a quiet and low vibration operation.
