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...

Wiper seal, also known as the dust ring, is a type of hydraulic seal. Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system. This is usually accomplished by a seal having a wiper lip that substantially removes any dust, dirt or moisture from the cylinder rod e...

A hydraulic seal is a relatively soft, non-metallic ring, captured in a groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications. Hydraulic seals are vital in machinery. Their use is critical in providing a way for fluid power to be converted to linear motion. They are widely used. Hydraulic seals material Generally Hydraul...

The T-seal is developed to replace the existing O-ring in the long-life hydraulic and pneumatic system, because the O-ring rolls in the sealing groove, which is easy to cause screw failure. Their ability to fit into existing grooves means they can be retrofitted without rework or major modifications to existing hardware designs, simplifying field changes and new equipment manufacturing. The T-seal...

The processing technology of turning seals is different from that of traditional molded seals. The raw materials for turning hydraulic seals are blank barrels formed by high-pressure extrusion of raw materials after heating and melting, and then the hydraulic seals are turned by special turning CNC seal processing equipment that programs various seal data through software. Turning hydraulic seals ...

Hydraulic seals are essential components in a hydraulic system as they help prevent leaks and ensure the smooth and efficient operation of the hydraulic system. What are the commonly used hydraulic seals? Hereby show you below: Hydraulic sealing systems include: O ring O-rings are the most commonly used hydraulic seals, and are suitable for a wide range of applications. Material typically made fro...

SPGW hydraulic seals are designed for heavy-duty applications, often used in hydraulic cylinders, offering a combination of wear resistance, low friction, and durability. Here are some key features of SPGW hydraulic seals: 1. Material: Bronze-filled PTFE (Polytetrafluoroethylene): Provides excellent resistance to wear, extrusion, and deformation. NBR/Nylon: Often combined with PTFE, these provide ...
