Rear Axle Air Tightness Inspection in Production

During the production process, rear axle air tightness inspection is a critical step to ensure long-term reliability and durability.

Each rear axle undergoes a dedicated sealing and air tightness test to verify the integrity of the housing and sealing components. By applying controlled air pressure and monitoring leakage, we are able to identify potential sealing issues before assembly and shipment.

This inspection helps prevent lubricant leakage, protects internal components, and ensures stable operation under various working conditions. Through strict quality control procedures at every production stage, we make sure that each rear axle meets our performance and reliability standards before delivery.

Quality is built in production — not only checked at the end.
