SEW KA67DRN100L4 Helical-Bevel Gearmotor
The SEW KA67DRN100L4 is a mid-range industrial helical-bevel gearmotor featuring a hollow shaft design[cite: 15]. Engineered for high mechanical efficiency, excellent fatigue resistance, and robust torque density, it is widely used in heavy conveyor systems, material handling, hoisting equipment, and industrial automation drives[cite: 15].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing application featuring an obsolete DT71, DT80, DT90, DV100, DV112, or DV132 motor, upgrading to an IE3 DRN motor ensures complete dimensional interchangeability while substantially reducing operating temperatures and energy costs[cite: 15]. 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[cite: 15].
