SEW FA157DRN280M4 Parallel Shaft Helical Gearmotor
The SEW FA157DRN280M4 is a maximum-capacity industrial parallel shaft helical gearmotor featuring a hollow shaft design[cite: 14]. Engineered for extreme torque demands, slender profile space envelopes, and heavy thermal endurance, it is extensively deployed in large mining conveyors, cement kiln drives, steel mill equipment, power plant material handling, and heavy agitator systems[cite: 14].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing application featuring an obsolete DV180, DV200, DV225, DV250, or DV280 motor[cite: 14], upgrading to an IE3 DRN motor ensures complete dimensional interchangeability while substantially reducing operating temperatures and energy costs. Simply send us your existing SEW serial number or nameplate code (including options like BE brake, TF thermistor, or RS backstop), and our engineering team will provide a 100% compliant replacement specification and quotation.
