SEW FA127DRN225M4 Parallel Shaft Helical Gearmotor
Brand: SEW-Eurodrive | Series: FA-Series (Parallel Shaft Hollow)
The SEW FA127DRN225M4 is a heavy-duty industrial parallel shaft helical gearmotor featuring a hollow shaft design[cite: 15]. Engineered for high torque output, high overhung radial capacity, and slim structural envelope demands, it is extensively deployed in bucket elevators, belt conveyors, cement machinery, heavy agitators, and bulk handling processing plants[cite: 15].

Expert Selection & Retrofit Engineering Notes
We specialize in providing complete drive packages and technical replacement solutions for the entire SEW-Eurodrive F127 series[cite: 15]. Whether you require a foot-mounted solid shaft unit (F127)[cite: 15], hollow shaft with keyway (FA127)[cite: 15], B5 output flange (FAF127 / FF127)[cite: 15], shrink disc connection (FH127)[cite: 15], or keyless TorqLOC® clamping system (FT127)[cite: 15], all mechanical designs can be supplied pre-assembled with state-of-the-art IE3 DRN series motors (DRN132M4 to DRN280M4)[cite: 15].
When retrofitting an existing application featuring an obsolete DV132, DV160, DV180, DV200, or DV225 motor[cite: 15], 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.
