Rotary Seal

A rotary seal is a mechanical component in rotating equipment that helps prevent leakage of lubricants like oil and grease while allowing for smooth rotation of the shafts. There are different types of such seals, each designed for specific applications. Common materials used for rotary seals include Silicon Carbide, Tungsten Carbide, Carbon Graphite, and ceramic. The most common type of rotary seal is the O-ring. In order to function properly, these seals must be properly installed and maintained as per the working applications.

How Does Rotary Seals Ensure the Sealing Performance

Rotary seals ensure the sealing of mechanical equipment per the principle of hydrodynamics. A lubricant, mostly oil or grease, is present between the seal and the shaft, which keeps the seals intact at their position. As the seal covers the outer part of the system, it disallows any external element to enter the system while maintaining the level of the lubricant.

  • Working Principle

The Rotary seal squeezes around the shaft, which is supposed to rotate during the normal functioning of the industry. But the lip of the shaft, the most important mechanical seal part, does not touch the shaft directly, as a layer of lubricant is present between the lip and the shaft. The lubricant ensures the proper and frictionless rotation of the shaft, while the seal can prevent any leakage. Rotary seals keep contaminants out of bearings and other sensitive components. The proper shaft rotation keeps the industry going, as the lubricant minimizes the friction between the shaft and the seal.

  • Applications 

Rotary seals are used in various applications where a rotating shaft needs to be sealed from outside contamination and preserve the lubricant.

One common application for rotary seals is in automotive engines. They are used to seal the gap between the piston and the cylinder wall. Similarly, these seals are also used in pumps, where they help to prevent leakage between the pump body and the rotating shaft. Another common application for these seals is in gearboxes, as they are used to close the gap between the gearbox housing and the rotating shaft. In addition, hydraulic cylinders, compressors, centrifuges, and blowers also employ seals. These seals are also employed in aircraft, cars, agricultural machinery, industrial grinders and crushers, and conveyor belts.

In fact, in the modern-day industrial setup, it is hard to name a single industry where rotary seals are optional.
