S Series Industrial Gearbox

The S series industrial gearbox combines a helical input stage with a worm output stage, achieving high reduction ratios while maintaining a compact footprint. This configuration provides the cost advantages of worm gearing with improved efficiency from the helical primary stage. ## Heavy-Duty Design The HT250 cast iron housing features extensive ribbing for heat dissipation and structural stiffness. All shafts run on high-quality tapered roller bearings rated for combined radial and axial loads, making the S series suitable for demanding applications such as conveyor drives in mining and quarrying. ## Cooling Options For continuous-duty applications, the S series can be equipped with: - External cooling fan with aluminum shroud - Oil cooler with circulation pump - Forced air cooling package These options extend the thermal power rating by 30-60% compared to natural cooling.
