Oil seals and mechanical seals serve different purposes in sealing applications. An oil seal is designed to prevent the leakage of lubricants and contaminants in rotating machinery, typically using a flexible lip that contacts a shaft. In contrast, a mechanical seal is used to prevent fluid leakage in rotating equipment, such as pumps or mixers, by utilizing a combination of stationary and rotating components that create a tight seal under pressure. While oil seals primarily focus on sealing against oils and greases, mechanical seals are engineered for more demanding applications involving various fluids and pressures.

What is purpose of mechanical seal on a compressor?

The purpose of a mechanical seal on a compressor is to prevent the leakage of fluids, such as refrigerants or lubricants, between the rotating shaft and the stationary housing. It ensures that the internal pressure is maintained while minimizing wear and tear on the components. Additionally, mechanical seals enhance the efficiency of the compressor by reducing the risk of contamination and maintaining optimal performance.


What is the difference between sealed bearings and shielded bearings?

Shield and seal are single or double walls to keep elements from entering into the bearing and grease from leaking. Unlike seal, shield allows a large gap thus fine elements can still go in. However, because of the non contact nature of shield, there is little loss in terms of torque and heat build-up. Seal on the other hand, because of the contact nature with the inner and outer rings, is better at keeping the elements out at the cost of torque and heat generation at high speed.
