Floating oil seals are essential components used in various industries to prevent leakage of oil and other fluids. These seals are designed to float on the surface of the oil, creating a barrier that keeps the oil contained within a system. They are commonly used in gearboxes, hydraulic systems, and other machinery where the potential for oil leakage is a concern.

Regular inspection and maintenance of 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 oil seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the equipment.

Table 5: The major special seals, their shapes, and their features

The oil pan seal, also known as the oil pan gasket, is a critical component in an automobile's engine system. It is responsible for sealing the oil pan to the engine block, preventing oil leaks and ensuring the proper lubrication of the engine. The seal oil pan plays a crucial role in maintaining the oil pressure and preventing the loss of lubricating oil, which is essential for the smooth operation and longevity of the engine.

The edge of the metal is finely ground after seal manufacture in a centerless grinder to enable an interference fit in the oil seal housing. A slight chamfer on the outer diameter (OD) of the seal is desirable for easy assembly. The sealing lip is prepared by buffing, grinding or cutting away the rubber flash which occurs at the sealing edge. A fine sealing edge creates sufficient pressure on the shaft to minimise spring load, leading to lower friction whilst maintaining effective seal performance. The garter spring plays an important role in the efficiency of the oil seal. If its tension is too high, heat will be generated between the sealing lip and the shaft, and result in rapid wear of the lip. If too low, the spring will be ineffective and the sealing lip will be worn away leading to leakage of the fluid.

5. Keep it clean

Describe difference between mechanical seal and oil seal – Whether it is a mechanical seal or oil seal, it prevents the fluid seeping the liquid to other parts of the machine, or it keeps the rotating parts lubricated.

Rubber type

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.
