SEW RF67 DRN80M4 Industrial Motor Gear Reducer

The RF67 Industrial Motor Gear Reducer is a high-performance inline helical gearmotor engineered for continuous, heavy-duty industrial power transmission. Combining a rugged helical gearbox with a high-efficiency IE3 electric motor, this unit delivers reliable torque transmission, exceptional thermal stability, and low operational noise under demanding environmental conditions.

The flange-mounted design ensures mechanical rigidity and compact integration, making it an optimal driving solution for conveyor systems, packaging machinery, industrial mixers, material handling equipment, automated production lines, and processing plants.

Our company manufactures precision-engineered compatible gear reducers featuring identical mounting dimensions, shaft tolerances, and electrical characteristics for seamless field replacement, backed by rapid global delivery and comprehensive technical support.

Precision Ground Hardened Gears: Carburized alloy steel gears with surface hardness up to HRC 58-62 deliver high tooth strength and minimal backlash.

Heavy-Duty Cast Iron Housing: Rigid HT250 cast iron enclosure provides exceptional structural integrity and vibration damping.

Premium Energy Efficiency: IE3-rated motor copper windings reduce energy losses and lower long-term power consumption.

Advanced Sealing Architecture: Dual-lip skeleton oil seals prevent oil migration and protect internal components from abrasive particles.

VFD Operation Ready: Reinforced motor insulation allows safe continuous operation with Variable Frequency Drives.

Quiet Drive Performance: Dynamically balanced rotor and precision-ground tooth profiles limit operational noise below 65 dB(A).

To accommodate diverse machinery layouts, the RF67 gear reducer can be specified in multiple mechanical configurations:

Mounting Orientations: M1 (Horizontal standard), M2 (Vertical shaft downward), M3 (Horizontal ceiling mount), M4 (Vertical shaft upward), M5, and M6 side mounts.

Output Shaft Types: Solid cylindrical output shaft with standard keyway, extended custom shafts, or stainless steel variants for corrosive environments.

Flange Sizes: Standard pitch circle diameter options matching global industrial machinery standards.

Conveyor Systems: Belt conveyors, roller conveyors, chain drives, and pallet transfer lines.

Packaging Machinery: Cartoning systems, shrink wrapping units, strapping machines, and automated palletizers.

Material Handling: Storage and retrieval systems, sorting equipment, overhead hoists, and transfer cars.

Process Industries: Agitators, fluid mixers, dosing pumps, and rotary feeders for chemical or food processing.

General Automation: Indexing tables, robotic positioning drives, and automated assembly equipment.

Each gear reducer undergoes systematic verification protocols prior to factory release:

Gear Geometry Inspection: Coordinate Measuring Machine (CMM) analysis to verify tooth profile, lead, and pitch accuracy.

Housing & Alignment Check: CNC machining tolerances are verified to ensure exact shaft centerline concentricity.

Full-Load & Run-In Testing: 100% operational testing to monitor noise levels, vibration limits, and bearing temperature stabilization.

Hermetic Seal Verification: Pressurized chamber leak testing guarantees zero oil leakage during transport and operation.

Protective Surface Treatment: Machined metal surfaces and output shafts receive temporary anti-corrosion wax coating.

Moisture Defense: Entire assembly is vacuum-sealed in heavy-duty polyethylene film with industrial desiccants.

Export-Grade Crate: Secured inside fumigation-free, heavy-duty plywood cases with foam padding to absorb shock during transit.
