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.

READ MOREShanghai SGR Heavy Industry Machinery Co., Ltd. is a China-based Cylindrical Worm Gear Reducer manufacturer and factory, specializing in the design and production of single-stage and double-stage cylindrical worm gear reducers. Our gearboxes are engineered for applications requiring high torque, compact mounting, and reliable right-angle power transmission, serving industries such as material handling, construction machinery, marine equipment, and industrial processing.
With over 15 years of gear transmission experience, we combine precision manufacturing with application-driven engineering. Our in-house R&D team, advanced CNC machining, and rigorous testing ensure that each reducer meets the specific demands of your machinery, whether you need a standard unit or a fully customized solution.
We offer two primary configurations to match different speed and torque requirements:
Provides a single reduction stage with ratios typically from 5:1 to 60:1. Ideal for applications needing moderate speed reduction and high torque output in a compact, right-angle package. Common uses include conveyor drives, rotary tables, and small hoists.
Combines two worm gear sets to achieve higher reduction ratios (up to 3600:1) while maintaining a compact footprint. Suitable for heavy-duty applications like crane slewing drives, mud pumps, and industrial mixers where high torque and low speed are essential.
Cylindrical worm gear reducers are chosen for their ability to provide high reduction ratios in a single or double mesh, with a 90-degree shaft orientation that simplifies machine layout. Our engineering team evaluates the specific duty cycle, shock loads, and environmental conditions to select the appropriate worm gear material, tooth profile, and lubrication method.
We have supplied gearboxes for projects including forklift attachments, crushers and shredders, cranes, trenchless horizontal directional drills, and palm oil processing equipment. This application breadth allows us to anticipate the stresses your reducer will face and design accordingly.
Each cylindrical worm gear reducer is built from high-strength materials selected for durability and wear resistance:
We apply tooth profile modification to optimize meshing, reduce vibration, and lower noise levels—a key requirement in modern industrial equipment. Our precision CNC machining ensures consistent tooth geometry, and each unit is tested on our power and efficiency test system before shipment.
We offer flexible configurations to integrate seamlessly into your machine design:
| Configuration Aspect | Options Available |
|---|---|
| Mounting | Foot-mounted, flange-mounted, shaft-mounted, or hollow output shaft |
| Input | Direct motor coupling, IEC B5/B14 flange, or input shaft with keyway |
| Output | Solid shaft, hollow shaft with shrink disc, or splined shaft |
| Accessories | Backstop, torque arm, cooling fan, or forced lubrication system |
For automation and control integration, we can supply reducers with encoder mounting provisions, proximity switch targets, or special shaft extensions for feedback devices. Our engineering team works with your control specifications to ensure the reducer matches your drive system's requirements.
As an ISO 9001 certified manufacturer, we maintain strict quality control throughout production. Each cylindrical worm gear reducer undergoes:
We also offer TUV CE approved test items based on IEC 61000 and IEC 62477 series standards for applicable electrical components. For custom projects, we can agree on specific acceptance criteria and provide test reports with the shipment.
Our reducers are designed for easy installation and long service life. We provide detailed installation manuals, lubrication charts, and maintenance schedules with every unit. Key maintenance points include regular oil level checks, oil changes at recommended intervals, and inspection of seals and bearings.
We stock spare parts for standard models and can supply replacement worm gear sets, bearings, and seals for quick field repairs. Our technical support team is available to assist with troubleshooting and to provide guidance on preventive maintenance programs.
Every order includes comprehensive documentation: dimensional drawings, installation and operation manual, test certificates, and material certifications. For complex projects, we can provide on-site or remote training for your maintenance team.
Our packaging is designed for safe export, with options for wooden crates, shrink wrapping, or custom protection for sensitive components. We coordinate shipping from our Shanghai factory, offering sea, air, or rail freight to destinations worldwide.
To prepare an accurate proposal and quotation, we need the following project information:
With this data, our engineers will select the appropriate size, ratio, and configuration to meet your performance and reliability targets.
Q: What is the difference between single-stage and double-stage cylindrical worm gear reducers?
A: Single-stage reducers provide a single reduction step, typically with ratios from 5:1 to 60:1, offering moderate torque increase. Double-stage reducers combine two worm gear sets to achieve much higher ratios (up to 3600:1) and significantly higher torque output, suitable for heavy-duty applications where space is limited.
Q: Can you customize a cylindrical worm gear reducer for a specific application?
A: Yes, we specialize in custom solutions. We can modify shaft dimensions, mounting arrangements, materials, and even tooth profiles to suit your exact requirements. Provide us with your load and speed data, and our engineering team will design a reducer that fits your machinery.
Q: What maintenance is required for your worm gear reducers?
A: Regular maintenance includes checking oil levels, changing lubricant at recommended intervals (typically every 10,000 hours or annually), inspecting seals for leaks, and monitoring for unusual noise or vibration. We provide a detailed maintenance manual with each unit.
Q: Do you provide test reports and quality certifications?
A: Yes, each reducer is tested on our power and efficiency test system, and we provide test reports upon request. Our factory is ISO 9001 certified, and we can supply CE certification for applicable models.
Q: What is the typical lead time for a custom cylindrical worm gear reducer?
A: Lead time depends on the complexity and quantity. For standard models, we typically ship within 2-4 weeks. Custom designs may require 4-8 weeks, including engineering and testing. We will confirm the exact lead time with your order.
