- The Importance of Center Bolt Valve Cover Gaskets
d1-d2, mm This refers to the component of the oil seal that makes contact with the shaft.
It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.- Nitrile oil seals offer several advantages over other types of seals. Their excellent resistance to hydrocarbons, such as gasoline, diesel, and lubricating oils, makes them ideal for automotive engines and transmission systems. Moreover, they exhibit good compression set resistance, ensuring a long-lasting seal even under constant pressure. Their ability to maintain their integrity in both cold and hot conditions further enhances their versatility.
Metal O.D. wall type (with a reinforcing inner metal case) Protects the main lip.
No matter the PTFE machining techniques and other processes used in making mechanical parts, they tend to fail due to some reasons. The same thing applies to oil seals. When they are exposed to some factors, they fail. The factors are stated below alongside the solutions.
Choosing Quality Oil Seals for Wheel Hubs and Steering Mechanisms
Investing in quality seals will benefit you and your machine in the long run. The cost of replacing oil seals will be higher as cheaper alternatives are constantly being purchased. Not to mention, the efficiency and quality of low-cost oil seals may not be reliable.
These oil seals are the best for applications involving high temperatures. It’s suitable for temperatures between -4 degrees Fahrenheit and 392 degrees Fahrenheit. Also, it’s highly resistant to acids, dissolvent materials, and other chemicals. Viton (FKM/FPM) oil seals can run at a maximum speed of 38 m/s.
