Hydraulic and Pneumatic
Hydraulic and pneumatic seals are used in a wide range of applications, from construction machinery, agricultural vehicles and aircraft to machine tools and production assembly lines.
Hydraulic cylinders are used in various industrial applications from various market segments including:
- Machine tools, injection moulding machines and presses
- Construction and earth moving equipment such as excavators
- Backhoes where they must prevent the ingress of aggressive media
- Agricultural vehicles where they must minimise leakage and corresponding soil contamination
- The smooth running of forest machinery
- Aircraft interiors where seals must meet safety requirements in critical applications
- Wind turbines where continuous 24/7 operation in extreme weather environments demands reliability
Case studies
Case
Description
Download60% Bronze Filled PTFE Seals
We were approached by a client who required seals for a large hydraulic lift. The lift had four identical cylinders of 11.5” bore with a 10.75” rod diameter.
DownloadSeals for Increased Production
This project involved hydraulic presses in a production environment, which were working, but the customer wanted to improve efficiency. The single acting seals being used were not leaking or causing any sealing issues; under pressure the rams were in production mode, when pressure was off, the ram retracted to its start position under its own weight, which was taking time. Our customer wanted to know if the retraction time could be reduced.
DownloadSolving Cylinder OEM Sealing Problems
The customer was having issues with new design, new build cylinders that were not passing tests, which subsequently was holding back an export delivery. After numerous stripping and re-sealing with seals and housings checked against drawings, failure was still being seen which could not be explained.
Hydraulic Hammer - KB26 Specialist Application
We were approached with a longstanding sealing problem, with an objective to replace the conventional O-Ring and Back-Up Ring arrangement with a superior sealing setup.
Some of the key contributing factors to the failure of the existing products included cavitation/dieseling effect, large pressure fluctuations, excessive short cycle movement and spiral/seal-roll failure.
Seals for Hydraulic Cylinders
The cylinder’s function directly affects the machine’s performance, so it is important that the seals are designed to limit contamination into the cylinder and ensure good wear performance.
However, the challenge facing seals in hydraulic applications extends far beyond this. In addition to preventing leakage, they must also endure and maintain integrity in high pressures, extreme temperatures, and transverse forces within the cylinder. Therefore, it is important that all the seals within the cylinder are designed to work together as effectively and efficiently as possible.
Our piston seals prevent leakage of pressurised hydraulic fluid from flowing across the piston and incorporate the use of a wear ring to prevent metal to metal contact whilst absorbing transverse loads. Meanwhile, our rod seas prevent leakage of hydraulic fluid as well as internal and external contamination. Scrapers are used to exclude dirt, foreign particles, and moisture from the system whilst a rod seal ensures sufficient lubrication for the piston rod.
