S Series Worm Gearbox Cast-Iron for Cement

Tailored for heavy-duty industrial scenarios such as cement production, mining, and quarrying, our S Series cast iron helical worm gearbox is a high-performance helical-worm speed reducer optimized for harsh working conditions. Adopting an advanced helical gear-worm wheel composite structure, this heavy-duty solution delivers significantly higher transmission efficiency and load-bearing capacity than single-stage worm wheel drives, with a compact design that saves installation space while achieving ultra-wide transmission ratios. It can be freely combined with various reducers and variators to meet the extreme load and impact resistance requirements of heavy industrial production, making it the ideal transmission choice for cement plants, mining operators, and heavy material handling enterprises.

Core Advantages of S Series Heavy Duty Cement Gearbox

Ultra-High Load & Impact Resistance for Harsh Environments

Built with a high-strength cast iron casing, our heavy duty gear reducer for cement features core gears made of 20CrMnTi alloy steel, processed by carburizing and quenching to reach a hardness of HRC58~62. With a maximum permitted torque of up to 4000N.m, it effectively resists strong impact and vibration during cement crushing, ore grinding, and heavy material conveying, ensuring stable long-term operation in dusty, high-load industrial environments.

Compact Structure & Wide Transmission Ratio Range

The optimized helical-worm arrangement achieves a compact structure with a transmission ratio range of 10.27-230.48, meeting the needs of different speed and torque requirements in cement production lines. Even in limited installation spaces, it can deliver high transmission performance, greatly reducing the difficulty of equipment layout and retrofitting.

Strong Compatibility & Interchangeability

This S Series cast iron helical worm gearbox is fully dimensionally and performance compatible with mainstream international brand reducers, making it a cost-effective replacement option for existing equipment. It supports multiple mounting methods, including foot mounting, flange mounting, hollow shaft mounting, and solid shaft mounting, adapting to various heavy industrial equipment configurations.
