Leakage is rarely caused by one factor
Seal damage, poor rod surface, bore roughness, contamination, pressure spikes, and assembly misalignment can all contribute to leakage in hydraulic cylinders.
Surface quality matters
Chrome plated rod surface finish and honed tube bore condition influence sealing performance. Buyers should not only check dimensions, but also ask about surface inspection and testing.
Pressure testing before shipment
Pressure and leakage testing helps confirm assembly condition before the cylinder is packed and shipped. It cannot replace correct design, but it reduces delivery risk.
FAQ
Yes. Dimensional checks, surface inspection, seal review, cleanliness control, assembly inspection, and pressure testing can reduce avoidable leakage risk.
