4. Outer Diameter The outer part of the seal fits snugly into the housing, preventing external contaminants from entering the system.
Preventive Measures
There is a wide variety of hydraulic piston oil seals, designed to meet specific operational demands. Some common types include
- Polyurethane (PU) Known for its toughness and high abrasion resistance, polyurethane seals are ideal for applications with high wear and tear.
3. Lip Seals These are utilized to protect rotating shafts and are effective in preventing dust and dirt from entering while retaining lubrication. They are commonly found in automotive applications.
Conclusion
- Nitrile Rubber (NBR) This material is resistant to oil and offers good elasticity, making it suitable for a variety of hydraulic applications.
