Product Overview
The KAF127 DRN200L4 helical bevel gear motor combines a precision-engineered reduction gearbox with a 30 kW high-efficiency electric motor to form a compact, high-torque industrial drive. Built around a right-angle transmission layout, this system provides optimized power conversion with thermal stability across extended continuous duty cycles.
Engineered with case-hardened alloy gears and rigid cast iron housings, the assembly absorbs mechanical shocks, minimizes operational noise, and resists deformation under full rated loads. The unit serves as a standard power unit for heavy conveyor networks, bulk material processing, and heavy processing machinery.

Key Performance Advantages
Precision Transmission Efficiency
Multi-stage helical-bevel gear geometry achieves over 95% mechanical efficiency per gear stage, generating significantly lower friction losses compared to traditional worm gear units.
High Power Density in Compact Footprint
The combination of optimized gear tooth profiling and high-grade materials delivers up to 9,260 Nm of torque within a compact frame, maximizing machinery space utilization.
Direct Dimensional Interchangeability
Designed around international mounting standards, the drive assembly offers direct physical interchangeability with standard KAF127 units, facilitating drop-in replacement during plant maintenance.
Reduced Energy Consumption
Integrated with an IE3 premium efficiency motor, the drive lowers continuous kilowatt usage, operational heat generation, and total lifecycle energy costs.
Reinforced Heavy-Duty Bearing Support
Heavy-duty tapered roller bearings handle high external radial and axial forces on the output shaft, protecting internal gearing from fatigue failure.
Customized Configuration Options
To support specific operating requirements, custom engineering modifications are available:
Electrical Adaptation: Custom motor windings for non-standard supply voltages (220V through 600V at 50Hz or 60Hz), explosive environment protection, or inverter-duty service.
Shaft & Interface Options: Custom output shaft diameters, keyless shrink discs, splined hollow shafts, and special mounting flanges.
Environmental Protections: Severe-duty outdoor painting systems, high-temperature Viton oil seals, stainless steel hardware, and anti-condensation heating elements
Engineering Quality & Inspection
Quality control procedures ensure field-proven reliability before shipment:
Gear Tooth Inspection: Computerized tooth profile, pitch error, and surface hardness testing (HRC 58-62).
Zero-Leakage Sealing Systems: Dual-lip shaft seals combined with ground sealing surfaces prevent oil leakage under heat and continuous shaft rotation.
Factory Performance Testing: 100% factory run-testing verifying backlash limits, vibration levels, operating noise, and steady-state oil temperatures.
Application Industries
The KAF127 DRN200L4 drive unit is deployed across heavy machinery sectors including:
Material Handling & Logistics: Long-distance overland belt conveyors, chain conveyors, bucket elevators, and heavy transfer cars.
Mining & Minerals Processing: Industrial crushers, vibrating screens, apron feeders, and slurry agitation tanks.
Environmental & Waste Management: Industrial shredders, wastewater clarifiers, sludgewater mixers, and waste compactors.
Bulk Material Processing: Cement plant machinery, clay pug mills, chemical blenders, and port unloading systems.
Packaging & Logistics Protection
All units are prepared for international shipping to prevent transit damage:
- Anti-corrosion wax film applied to exposed shafts, keys, and mounting faces.
- Sealed, moisture-resistant protective plastic barrier wrapping.
- Heavy-duty, ISPM-15 compliant heat-treated fumigation-free wooden cases designed for forklift handling and ocean freight stability.
