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.

To ensure optimal performance, we consider the following parameters when configuring your gearbox:
| Parameter | Typical Range | Application Impact |
|---|---|---|
| Ratio | 3.15 – 7800 | Determines output speed and torque |
| Output Torque | 1500 Nm – 540,000 Nm | Matches load requirements |
| Input Power | Varies by model | Ensures motor compatibility |
| Mounting Position | M1 – M6 | Affects installation and lubrication |
| Center Distance (Worm) | 100 – 710 mm | Defines size and torque capacity |
Our gearboxes can be configured with various input options (electric motor, hydraulic motor, or shaft input) and output arrangements (solid shaft, hollow shaft, or flange). For automation systems, we offer low-backlash planetary gearboxes suitable for servo applications, ensuring precise positioning and repeatability.
We also provide gearboxes with integrated brakes, encoders, and other accessories to meet your control requirements. Our team can assist with the selection of couplings, belts, and other transmission components to ensure a complete drive solution.
Every gearbox undergoes rigorous testing before shipment. Our in-house laboratory is equipped with a coordinate measuring machine and a power and efficiency test system, allowing us to verify dimensional accuracy, noise levels, and efficiency under load. We also perform full inspections according to your requirements, and our quality management system is ISO 9001 certified.
