Excavator Hydraulic Cylinder Testing Standards

Before leaving our factory, every hydraulic cylinder undergoes strict pressure testing to ensure reliability and durability in demanding applications. The testing process focuses on three key aspects:

Sealing Integrity – Both internal and external seals are tested under pressure to confirm there is no leakage.

Load-Bearing Capacity – The cylinder is subjected to working pressure levels to verify it can withstand the designed load.

Weld Strength & Structural Integrity – All welded joints are carefully inspected under pressure to ensure complete durability.

Testing Procedure:
Each cylinder is placed on a hydraulic test bench, where pressure is gradually applied during operation. Once the cylinder reaches the required test pressure, technicians carefully check for any signs of leakage through the seals or welded areas. Only cylinders that pass all stages are approved for shipment.
