Three Stage Reducer Zq 500 Industrial Gearbox

The ZQ series reducer comes with a 12-month warranty from the date of delivery. This warranty covers defects in materials and workmanship under normal operating conditions; damage caused by improper use, maintenance, or external force is not included.

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.

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.

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).

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.
