What is a common feature of mechanical seals?

A common feature of mechanical seals is their design to prevent fluid leakage, particularly in rotating machinery such as pumps or compressors. These seals rely on a precise fit between several components, and a set screw plays a key role in securing the stationary part of the seal to the housing. This ensures that the seal remains properly aligned during operation, which is essential for maintaining the integrity of the seal and preventing leaks.

Additionally, the set screw helps to absorb any vibrations or movements that might occur during operation, enhancing the seal's performance and longevity. While locking mechanisms, adjustable collars, and ball bearings may be components found in various mechanical assemblies, they do not specifically characterize the function and purpose of a mechanical seal in the same way that a set screw does. This makes the set screw a fundamental and common feature associated with mechanical seals in ensuring their effectiveness in various applications.
