China ZQ, JZQ Cylindrical Gearbox Speed Reducer - Top Suppliers & Factory Direct Products
Product Features
1
The reducer is used for both forward and reverse operation.
2
The reducer has nine types of transmission ratios, nine configuration types and three low-speed shaft types.
3
The transmission ratios of this type of reducer are:
48.57 | 40.17 | 31.5 | 23.34 | 20.49 | 15.75 | 12.64 | 10.35 | 8.23
48.57 | 40.17 | 31.5 | 23.34 | 20.49 | 15.75 | 12.64 | 10.35 | 8.23
4
The extended model can achieve a larger transmission ratio by adding a high-speed stage:
317.28 | 291.19 | 243.86 | 223.80 | 191.22 | 163.38 | 141.73 | 121.10 | 92.21 | 81.70 | 65.54
317.28 | 291.19 | 243.86 | 223.80 | 191.22 | 163.38 | 141.73 | 121.10 | 92.21 | 81.70 | 65.54
Conditions of Use
⚙️
The circumferential speed of the gear transmission in the reducer shall not exceed 10 meters per second.
🔄
The rotational speed of the high-speed shaft shall not exceed 1,500 revolutions per minute.
🌡️
The working environment temperature of the reducer ranges from −40℃ to +40℃.
Maintenance
1
Regularly check the oil level: Check the oil level once a month or every 500 hours of operation to ensure it is within the specified range.
Regularly change the lubricating oil
- First oil change: The first oil change should be carried out 36 hours after the first operation to remove the metal shavings produced during the running-in period.
- Subsequent oil change: Depending on the working environment and load conditions, replace lubricating oil every 2,000 to 5,000 hours of operation or every 6 to 12 months. In harsh environments (high temperatures, much dust, continuous heavy loads), the oil change cycle should be shortened.
- Oil change method: When the reducer is still warm (the lubricating oil has good fluidity), drain the old oil and add new oil to the specified oil level.
3
Keep clean and ensure the vent cap is unobstructed: Regularly clean the oil stains and dust on the surface of the reducer, and inspect and clean the vent cap to prevent blockage.
4
Fastening inspection: Regularly check whether all installation bolts and connecting parts are loose.
⚠️
Abnormal situation handling: Once a sudden increase in noise, intensified vibration, abnormal temperature rise or severe oil leakage is detected, the machine should be stopped immediately for inspection. Operation can only resume after the fault has been eliminated.

Frequently Asked Questions
Q1
What transmission ratios are available for the ZQ/JZQ reducer?
The standard model offers nine transmission ratios: 48.57, 40.17, 31.5, 23.34, 20.49, 15.75, 12.64, 10.35, and 8.23. The extended model with an additional high-speed stage can achieve even larger ratios ranging from 65.54 up to 317.28.
Q2
Can the ZQ/JZQ reducer be used for both forward and reverse operations?
Yes. The ZQ/JZQ reducer is designed to support both forward and reverse operations, making it suitable for a wide range of industrial applications that require bidirectional movement.
Q3
What is the maximum allowable rotational speed for the high-speed shaft?
The rotational speed of the high-speed shaft must not exceed 1,500 revolutions per minute (RPM). Exceeding this limit may result in accelerated wear or equipment damage.
Q4
What is the recommended operating temperature range for the reducer?
The working environment temperature for the ZQ/JZQ reducer ranges from −40℃ to +40℃. For environments outside this range, additional protective measures or specialized lubricants may be required.
Q5
How often should the lubricating oil be changed?
The first oil change should be performed 36 hours after initial operation. Subsequently, oil should be replaced every 2,000 to 5,000 hours of operation or every 6 to 12 months. In harsh environments such as high temperatures, dusty conditions, or continuous heavy loads, the oil change interval should be shortened accordingly.
Q6
What should be done if abnormal noise or vibration is detected during operation?
If you notice a sudden increase in noise, intensified vibration, abnormal temperature rise, or severe oil leakage, stop the machine immediately. Do not resume operation until a thorough inspection has been completed and the underlying fault has been fully resolved.
