We recently got a quality complaint from customer that the hydraulic rod was burn during working, see below photo. After analysis with our engineering team, we call this “Diesel Effect”. We’d like to discuss about this. What is the “diesel effect”? The diesel effect occurs in a hydraulic cylinder when air is drawn past the rod seals, mixes with the hydraulic fluid and explodes when pressurized. Ho...

A hydraulic cylinder seal is a critical component in hydraulic systems, designed to prevent fluid leakage and maintain pressure within the cylinder. These seals ensure the efficient operation and longevity of hydraulic cylinders by keeping the hydraulic fluid contained and separating different fluid areas to avoid contamination. Types of Hydraulic Cylinder Seals 1.Rod Seals: Prevent fluid leakage ...

In hydraulic and pneumatic seals, main seals such as O-rings receive much attention, but their performance relies on an often overlooked component: the back up ring.   What is a Back up Ring? A back up ring is a rigid ring installed next to the seal to prevent it from being squeezed into the metal gap under high pressure. Back up rings are essential when system pressu...
