A gear reducer,also commonly know as a gearbox, is a mechanical device used to increase torque while decreasing speed between two rotating shafts. This change in speed-to-torque ratio allows machines to operate more efficiently and safely.
SGR gear reducers are known for their reliability, efficiency, and durability. They offer superior performance and are crafted using cutting-edge technology, which makes them suitable for a wide range of industrial and mechanical applications.
When selecting a gear reducer, consider factors such as the required speed and torque output, the operating environment, and the type of motor or machinery it will be connected to. You can also directly consult SGR technical expert.
Most gear reducers can handle a range of operating conditions, extremely high temperatures may affect their performance and lifespan. Special high-temperature gear reducers are available for such environments.
Regular inspection, lubrication, and replacement of worn parts are key to maintaining your speed reducer. SGR provides guidelines for maintenance when you buy gear reducers.
Failure of a gear reducer can lead to a reduction in machinery efficiency, excessive noise, and even machinery breakdown. Regular maintenance and inspections can prevent most failures.
SGR gear reducers can be purchased directly from SGR factory. Request a quote or contact us at any time.
With proper maintenance and under normal operating conditions, SGR gear reducers can last for many years. The exact lifespan depends on usage and environmental factors.
Yes, SGR offers custom solutions to meet unique operational requirements in different industries. If you need customized reducer solutions, feel free to contact with us.

READ MOREShanghai SGR Heavy Industry Machinery Co., Ltd. — precision-engineered toroidal worm gear reducers for demanding industrial applications.
We are a China-based Single-Stage Toroidal Worm Gear Reducer manufacturer specializing in double-enveloping worm gear technology. Our reducers deliver high torque density, smooth operation, and long service life for applications ranging from mining and construction to marine and renewable energy. With over 15 years of engineering experience and a dedicated R&D team, we provide both standard and fully customized solutions.
Our product range covers center distances from 100 mm to 710 mm with speed ratios i ≥ 10, designed to meet the most demanding industrial requirements. We focus on compact, modular, and standardized designs that reduce vibration and noise while maximizing efficiency.
Our single-stage toroidal worm gear reducers are available in multiple configurations to suit various installation and performance needs. We offer different mounting styles, shaft arrangements, and input options, including motorized versions.
| Model Series | Center Distance (mm) | Speed Ratio | Typical Application |
|---|---|---|---|
| C Series | 100 – 710 | i ≥ 10 | Heavy-duty conveyors, mixers |
| High-Efficiency Series | 125 – 500 | 10 – 60 | Energy-sensitive processes |
| Heavy-Duty Series | 200 – 710 | 10 – 100 | Crushers, cranes, marine winches |
Our R&D team, including PhDs and senior engineers, has developed proprietary optimization systems for double-enveloping worm gear design. This ensures precise tooth geometry, maximum contact, and superior load distribution.
We operate a comprehensive quality management system certified to ISO 9001. Each reducer undergoes rigorous inspection, including dimensional checks with coordinate measuring machines and performance testing on our power and efficiency test platform.
Our factory in Shanghai is equipped with advanced machinery, including CNC machining centers and specialized grinding machines, ensuring consistent quality and precision.
Single-stage toroidal worm gear reducers are ideal for applications requiring high torque at moderate speeds, right-angle power transmission, and compact design. They are widely used in:
We understand that every application has unique requirements. Our engineering team works closely with you to customize shaft extensions, mounting flanges, input configurations, and even special materials for corrosive or high-temperature environments.
We also provide integration support, including motor adapters, backstops, and torque arms, ensuring seamless installation into your existing system.
To prepare an accurate proposal, we need the following details:
Each reducer is supplied with detailed installation and maintenance manuals. Our support team provides guidance on alignment, lubrication, and periodic inspections to maximize service life. We offer spare parts and after-sales service globally.
Efficiency varies with ratio and load, but our optimized designs achieve up to 90% efficiency at favorable ratios, significantly higher than conventional worm gears.
Yes, we can supply reducers with special seals, non-sparking materials, and appropriate certifications for hazardous environments. Please specify your zone classification.
Lead time depends on complexity and quantity. Typically, standard models ship within 30 days, while custom designs may take 45-60 days. We confirm exact timelines in our quotation.
All our gearboxes come with a 1-year warranty against manufacturing defects. We also provide extended warranty options for critical applications.
We implement strict process control and final inspection per batch. For large orders, we provide pre-shipment inspection reports and can arrange third-party verification if required.
