This F Series parallel shaft helical gear reducer features a high-strength cast iron housing and precision helical gear transmission structure. It supports multiple mounting configurations including solid shaft output and flange output, offering flexible adaptation to diverse equipment layouts. Characterized by high transmission efficiency, low operational noise, and substantial torque capacity, it delivers stable performance under complex conditions. Paired with standard motors, it achieves efficient speed reduction and torque amplification, serving as a core power transmission component for industrial equipment.

Professional Air Tightness Testing

Each reducer undergoes air tightness testing before painting to minimize oil and air leakage rates! Ensuring Jilian reducers deliver long-lasting, reliable operation—quality you can trust, peace of mind for customers!

Housing Machining Process

Metal mold mechanical shaping → Production line casting → Manual aging treatment → Shot blasting → Machining center processing → Coordinate measuring machine inspection

Gear Machining Process

Forging → Normalizing → Rough Turning → Finish Turning → Gear Hobbing → Chamfering Gear Ends → Carburizing & Quenching (HRC 58-62) → Shot Blasting → Grinding End Faces & Bore → Gear Grinding → Precision Inspection (Tooth Profile, Tooth Direction, Pitch, etc., Grade 6)

→ Wire Cutting Keyway → Magnetic Particle Inspection → Ultrasonic Cleaning & Rust Prevention

Shaft Machining Process

Forging → Normalizing → Rough Turning (including center hole drilling) → Finish Turning → Gear Hobbing → Keyway Milling → Carburizing and Quenching (HRC58-62) → Shot Blasting → Center Hole Finishing → Outer Diameter Grinding → Gear Grinding → Inspection (Tooth Profile, Tooth Direction, Pitch, etc., Grade 6) → Magnetic Particle Inspection → Ultrasonic Cleaning and Rust Prevention
