The design and material of a shaft oil seal are crucial factors in determining its effectiveness and durability. High-quality seals are made from durable materials that can withstand high temperatures, pressures, and speeds. They are also designed to maintain a tight seal against the shaft while allowing for smooth rotation without excessive friction or wear.
Benefits include:
Oil seals go by many names, such as shaft seals, dirt seals, grease seals, lip seals, and many other variations of these. They are essentially simple devices used in rotary shaft equipment to prevent lubricant from escaping and for excluding contaminants such as dust, dirt and water. An oil seal’s most important function, however, is that it protects every type of ball, sleeve and roller bearing in the rotating shafts. The seals also prevent the integration of two different fluids that shouldn’t mix, such as oil and water.
Heat resistance
The oil seal should be tough enough to withstand the pressure and the vibrations caused by the shaft and bore. Check if the oil seal is strong enough to tolerate the pressure and vibration.
It is important to regularly inspect and replace worn-out piston oil seals to ensure the proper functioning of the engine. This can help to prevent costly repairs and extend the life of the engine.
Lubricant can be retained in the space between the main lip and the minor lip.
Free the cover by levering gently round the edge with a screwdriver; take care not to bend the flange.
Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.
