Foshan Nanhai Zhujiang Reducer Co., Ltd.

Foshan Nanhai Zhujiang Reducer Co., Ltd. was established in the late 1980s and is located in the North Park Industrial Zone, Xingye North Road, Nanhai Economic Development Zone (Shishan Park), Shishan Town, Nanhai District, Foshan City, Guangdong Province. Currently, the company has more than 280 employees, including over 30 mid- and senior-level technical personnel, among whom 10 are senior engineers. The company covers an area of 50,000 square meters and has a building area of approximately 50,000 square meters. It specializes in the production of various types of reducers and is one of China's major reducer manufacturers, enjoying a high reputation within the industry.

The gearbox produced by our company is a power transmission mechanism that uses a gear speed reducer to decrease the rotational speed of the motor to the desired level while simultaneously increasing the torque. In mechanisms used for transmitting power and motion, gearboxes find applications across a remarkably wide range. From heavy-duty power transmission tasks to applications involving small loads and precise angular transmissions, gearboxes are ubiquitous. Moreover, in industrial applications, gearboxes serve not only to reduce speed but also to increase torque. Consequently, they can be widely employed as devices for converting between speed and torque.

Foshan Nanhai Zhujiang Reducer Co., Ltd.

Our current primary processing equipment includes nearly 200 precision machines—such as vertical and horizontal machining centers, CNC gear-grinding and gear-hobbing machines, and CNC lathes and milling machines—as well as 70 conventional machining devices. We are also equipped with advanced precision testing facilities, including a gear-testing center and a three-coordinate measuring center, to closely monitor the condition of workpieces. As the company continues to grow, we constantly optimize both our processing and product structures. Our processing equipment boasts cutting-edge technology and considerable scale, making us unique and highly competitive among domestic peers, especially within Guangdong Province. By leveraging advanced technologies such as CNC and programmable systems, we ensure that the stability of our machined parts remains consistently at a high level. As a result, our products enjoy a broad consumer base spanning woodworking machinery, glass machinery, food machinery, packaging machinery, ceramic machinery, the power industry, and a wide range of general-purpose machinery sectors—and have earned widespread market recognition for their consistent quality and reliability.

The company continuously develops new products every year and has been awarded numerous national patents, provincial and municipal science and technology progress awards, as well as honors such as “Guangdong Province Private Science and Technology Enterprise,” “Eagle Plan” Key Supported Enterprise, “China Credit Enterprise Certification System Demonstration Unit,” “Foshan City Class A Enterprise for Standardized Safety Production Management,” “High-Quality Brand Enterprise,” and “Premium Supplier Member.” In 2014, the company was granted the title of Guangdong Province Famous Trademark, and in 2015, it successfully passed the first batch of Provincial High-Tech Enterprise Cultivation Projects. In 2019, the company was recognized as the Guangdong Province Engineering Technology Research Center for High-Performance, Environmentally Friendly, and Precision Gear Reducers.

Frequently Asked Questions

What are some advantages of certain ground gears?

What are some advantages of certain ground gears?

Some advantages are: quenched and ground gears—1. Noise reduction 2. Maximizing efficiency 3. Higher load-carrying capacity 4. Modified tooth profile—longer service life.

When do you use helical gear reducers or worm gear reducers?

When do you use helical gear reducers or worm gear reducers?

Worm gear reducers are used for applications ranging from low to medium horsepower. They offer low cost, high reduction ratios, and high output torque in a compact package. They exhibit greater tolerance to shock loads compared to helical gear reducers. Helical gear reducers, on the other hand, are suited for high-horsepower applications where long-term operational efficiency is more critical than initial investment costs.

What do you mean by “hand driving”?

What do you mean by “hand driving”?

The position of the output shaft relative to its reducer input shaft is referred to as the configuration of the hand. This is commonly designated as right-handed (J), left-handed dominant (G), or ambidextrous (H) if the output shaft is doubly extended.

What are the two main reasons for the premature failure of gear reducers?

What are the two main reasons for the premature failure of gear reducers?

Some of the most common causes include improper selection of a failed reducer for the application, changes to the motor’s horsepower or speed, incorrect alignment of couplings, improper operation or insufficient lubrication, and a lack of regular maintenance and repairs.

Is it advantageous for the application to use synthetic lubricant in the transmission?

Is it advantageous for the application to use synthetic lubricant in the transmission?

Most synthetic lubricants have lower pour points, high resistance to oxidation, and are more readily compatible with additives than conventional oil-based lubricants. Therefore, a gearbox will benefit from using synthetic lubricants under any of the following conditions: extremely hot or cold ambient temperatures; heavy-duty applications involving difficult-to-handle loads; continuous operation under demanding conditions; or limited lubrication intervals.

Is a worm gear reducer “self-locking”?

Is a worm gear reducer “self-locking”?

A worm gear set is considered self-locking—or non-reversible—when the worm cannot drive the gear. Under this condition, if the lead angle of the worm is less than the friction angle, the efficiency of reverse driving becomes zero. In static conditions, factors such as the friction angle, surface finish, and lubrication can all influence these values. The generally accepted reference value is...
