SEW FHF127 DRN160M4 High Torque Parallel Reducer

The FHF127 DRN160M4 High Torque Parallel Shaft Helical Gear Reducer is a heavy-duty industrial drive designed for demanding mechanical transmission applications that demand high output torque, continuous load capacity, and operational stability.

Constructed on a parallel shaft architecture, this gearbox combines high-density helical gearing with an energy-efficient DRN160M4 11 kW (15 HP) 4-pole electric motor. The streamlined interior configuration optimizes efficiency while maintaining high thermal dissipation. Standardized mounting interfaces ensure full physical interchangeability for machine retrofits, engineering replacements, and system upgrades without requiring structural modifications.

Engineered to operate reliably under severe radial loads and severe environmental shock, this drive system supports heavy-duty conveyors, industrial crushers, steel processing lines, and high-capacity fluid agitators.

Optimized High-Torque Gear Geometry
Carburized alloy gears undergo computerized tooth profile modifications (tip and root relief) to eliminate local stress concentrations, enabling high shock load resistance and thermal stability.

High Mechanical Efficiency & Quiet Operation
Precision helical grinding minimizes mesh friction, achieving transmission efficiency above 95% per gear stage while operating below 75 dB(A).

Reinforced Heavy-Duty Housing
High-rigidity cast iron housing effectively dampens vibration, preserves shaft centerlines, and resists mechanical deformation under full load conditions.

Advanced Leakage Defense & Bearing Support
Integrated Viton (FKM) double-lip oil seals combined with heavy-duty tapered roller bearings protect against lubricant leakage and shield internal components from dust ingress.

Flexible Modular Mounting
Multi-axis mounting structures accept diverse output options, including solid shafts with parallel keys, hollow shafts with shrink discs, or standardized torque arms.

Material Handling & Bulk Transport
Overland belt conveyors, bucket elevators, automated storage machinery, and port unloading cranes.

Mining, Quarries & Construction
Vibrating screen feeders, jaw crushers, ball mills, and aggregate transport systems.

Metals & Heavy Processing
Steel rolling tables, coil winding equipment, continuous casting lines, and plate bending machinery.

Chemical & Wastewater Processing
Industrial fluid mixers, sludge agitators, rotary thickeners, and waste treatment screens.

Initial Oil Change
Perform the first lubricant flush and oil replacement after 500 operating hours to eliminate break-in particulates.

Regular Maintenance Schedule
Under standard operating conditions , replace mineral gear oil every 4,000 operating hours or every 2 years. For synthetic lubricants (ISO VG220/320 Polyglycol/PAO), extend replacement to every 10,000 operating hours.

Mounting Position Adjustment
Fill volumes vary depending on mounting orientation (M1 to M6). Verify oil level via sight plug inspection windows prior to initial startup.

Custom engineering solutions available include:

Tailored Reduction Ratios
Precise multi-stage gear ratio design tailored to exact output speed specifications.

Custom Shaft Connections
