Sumitomo Paramax® 9000 Heavy Industrial Gearboxes
The Sumitomo Paramax® 9000 Industrial Gearbox Series (featured model: P9040 Parallel 2-Stage Helical Gearbox) represents Sumitomo's pinnacle modular heavy drive platform, engineered specifically for high-torque, heavy-duty continuous industrial operations in mining, cement kilns, bulk material handling conveyors, pulp digesters, and cooling towers. Designed with **carburized, precision-ground gearing using a 25° tooth pressure angle**, Paramax 9000 gearboxes deliver exceptional bending strength, high fatigue limits, and quiet power transmission. Built with high-rigidity cast-iron housings optimized for enhanced thermal dissipation, these units incorporate axial cooling fans, internal oil lubrication channels, and optional water cooling coils. Available in **Parallel Shaft (2, 3, and 4-stage helical)** and **Right-Angle Shaft (2, 3, and 4-stage bevel-helical)** configurations across 26 distinct frame sizes (Paramax 9020 to 9110), covering torque ratings up to **550,000 Nm** and gear ratios from 1.25:1 to 500:1. WE DRIVE HONGKONG LIMITED provides technical sourcing, ratio calculations, and 100% compliant mechanical replacement support for legacy **Sumitomo Paramax 7000 and Paramax 8000** industrial gearboxes.
