04/

Sliding Surface Oil Seal
These oil seals are designed for sealing various sliding surfaces, such as those found in hydraulic breaker mechanisms. Their structure and materials can be customized to meet specific sealing requirements.

05/

Wiper Seals
Wiper seals are positioned on the external side of the hydraulic breaker and serve to remove dirt, dust, and other contaminants from the piston rod as it retracts into the cylinder. They help to protect the rod seals and extend their lifespan.

06/

Guide Rings/Bands
Guide rings or guide bands are used to guide the piston rod and maintain its alignment within the cylinder. They provide support and reduce friction between the rod and cylinder wall.

Main Functions of Kedias Oil Seal

 

Preventing Oil Leakage
Oil seals are primarily designed to create a tight seal between moving parts, preventing lubricating oil from escaping the system. In a hydraulic breaker, this is crucial as oil leakage can lead to reduced lubrication, increased wear and tear, and potential system failure.

 

Maintaining Pressure Integrity
The oil seals in a hydraulic breaker help maintain the integrity of the hydraulic pressure within the system. By preventing leaks, they ensure that the hydraulic fluid remains under the required pressure, enabling the breaker to operate effectively.

 

Reducing Contamination
Oil leaks can not only deplete the system of lubricating oil but also allow contaminants such as dirt, dust, and debris to enter the system. Oil seals prevent this ingress, keeping the hydraulic fluid clean and reducing the risk of wear and damage to internal components.

 

Enhancing System Efficiency
By maintaining the correct oil levels and pressure, oil seals contribute to the overall efficiency of the hydraulic breaker. They help ensure that the breaker operates smoothly, with minimal friction and wear, leading to improved performance and longer component lifespan.

 

Reducing Maintenance Costs
Preventing oil leaks and maintaining system integrity helps reduce the need for frequent maintenance and repairs. This, in turn, saves money on replacement parts and labor costs, making the hydraulic breaker more cost-effective in the long run.

 

Protecting Internal Components
Oil seals act as a barrier, shielding internal components from external debris and contaminants. This protection ensures that critical parts, such as pistons and seals, remain free from damage, extending their useful life.
