Seal characteristics
Regular inspection and maintenance of engine oil seals, power steering oil seals, and motor oil seals are essential to identify signs of wear, damage, or leakage. Proper lubrication and adherence to recommended service intervals can help extend the lifespan of these seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the vehicle's systems.
Dimensions
In conclusion, the piston oil seal is a critical component in an internal combustion engine. It plays a vital role in preventing oil leakage, reducing friction, and ensuring efficient engine operation. Regular inspection and maintenance of the piston oil seal are essential for maintaining the performance and longevity of the engine.
ERIKS also supplies the types GR and GRST. These are virtually identical to the types R and RST, except in this case the metal inner ring is also completely encased in rubber. ERIKS uses FKM rubber here as standard, so these seals are ideal for use in acidic environments.


Materials Used to Make Oil Seals
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)
DIN
An oil seal is designed to perform three major functions: to prevent lubricants from leaking outside the seal even under high pressure, to act as a barrier to retain the lubricating oil, and to prevent dirt and other contaminants from entering the unit.
