Eliminate Load Failures and Gearbox Downtime
In high-demand industrial environments such as brick manufacturing, mining, and petrochemical processing, gearbox performance under extreme torque loads is critical to operational continuity. Many facilities still rely on outdated or under-specified reducers, resulting in mechanical failures, poor energy transmission, and unplanned stoppages. The Motovario H Series Helical Gear Reducers, supplied by Madacan Africa, are precision-engineered to mitigate these risks. Offering modular flexibility, axial/radial load capacity, and torque ratings up to 23,000 Nm, these units provide consistent mechanical power transmission under the harshest working conditions—ensuring system stability and uptime across South Africa’s toughest industries.
Engineered for Continuous Duty Under Extreme Torque
The H Series delivers superior mechanical efficiency through hardened, ground helical gears, ensuring smooth meshing, reduced frictional losses, and minimal backlash. Built for continuous duty (S1) applications, the gear reducers maintain output integrity under fluctuating loads, shock vibrations, and high thermal gradients typical of brick extruders, vibratory feeders, and aggregate crushers. Housings are manufactured from high-strength cast iron (EN-GJL-200) with integrated cooling fins, enhancing heat dissipation for sustained thermal stability. Input/output shaft configurations include solid keyed shafts, hollow bores, and IEC motor adapters, making integration seamless into new or retrofit plant systems.
Modular Design for Seamless Plant Integration
The H Series supports multiple mounting positions—B3, B5, B6, B7, V5, V6—and is fully compliant with IEC and NEMA motor interface standards, allowing for flexible integration across both legacy and modernised systems. Gear ratios range from 1.25:1 to 450:1, enabling precise speed regulation across varied applications such as kiln drives, screw conveyors, drag chains, and chemical agitators. The units also accommodate radial loads up to 60,000 N on the output shaft, making them a strong fit for high-inertia start-up systems common in oil & gas and energy storage plants. Madacan Africa offers full technical support, 3D CAD downloads, and consultation to simplify system design and reduce engineering lead time.
