Product Description

ZQ Series Reducer: High-Torque, Durable Solution for Industrial Heavy-Duty Applications

The ZQ series reducer is a reliable cylindrical gear reducer, trusted in industries for robust performance. It enables efficient speed reduction and torque amplification, ideal for heavy-duty tasks in mining, metallurgy, construction, and conveyors.
The ZQA series reducer (a key variant) boosts gear precision and load capacity for high-intensity use. The complementary JZQ gearbox shares its cylindrical gear design, ensuring industrial machinery compatibility. For high-torque needs, the ZQ 500 gearbox stands out—it uses a three-stage involute reducer structure for smooth transmission, low noise, and long life under heavy loads.
Its three-stage involute reducer core ensures stable meshing, minimal wear, and over 95% efficiency, critical for energy savings. As a high-torque reducer, it converts high input speeds to low-speed, high-torque output, fitting mixers and crushers.
Designed as a base-mounted reducer, it simplifies setup, ensures precise alignment, and reduces vibration—lowering maintenance costs. As an industrial gearbox, it withstands harsh conditions (-40℃ to 40℃, dust, humidity) via a durable housing.
Rigorously tested as a heavy-duty gear reducer, it runs continuously without performance loss (needing L-CKC100/320 oil lubrication). Alongside ZQA series and JZQ gearbox, it delivers cost-effective performance for industrial transmission.
Suitable for small lines to large mining ops, it embodies top cylindrical gear reducer traits, meeting diverse needs and remaining a global buyer favorite.

A:Yes, customized production is available for the ZQ series reducer. We can adjust parameters such as transmission ratio, output torque, installation dimension, shaft extension type, and material (e.g., high-strength alloy for harsh environments) to match your unique application requirements.

3,
Q:What does the 12-month warranty for the ZQ series reducer specifically cover?
A:The 12-month warranty covers failures or malfunctions resulting from inherent manufacturing defects, such as abnormal wear of internal gears (without external damage), bearing failure (due to quality issues), or leakage of the reducer casing (caused by poor sealing during production). It does not cover consumable parts (e.g., oil seals) or damage from overload, corrosion, or unauthorized modification.

4,
Q:What information do I need to provide when requesting customized ZQ series reducers?
A:To ensure accurate customization, please provide the following key information: required transmission ratio, rated output torque, input/output speed, installation space constraints (e.g., length, width, height), shaft extension specifications (diameter, length, keyway size), operating environment (temperature, humidity, dust level), and any special requirements (e.g., explosion-proof, waterproof).

5,
Q:If a ZQ series reducer has a problem within the 12-month warranty period, how should I apply for after-sales service?
A:First, contact our after-sales team with your order number, delivery date, and detailed descriptions of the problem (e.g., abnormal noise, oil leakage, reduced efficiency). Our team may request photos or videos of the faulty part for preliminary diagnosis. If confirmed as a warranty-covered issue, we will arrange for repair, replacement of defective components, or even a full unit replacement (depending on the severity of the problem) at no additional cost.
