What is the ideal psi range for an air tight bearing protector?

The ideal psi range for an air tight bearing protector is typically between 5 to 10 psi. This range provides enough pressure to keep contaminants like dirt and water out of the bearings while not being so high that it risks damaging the seals or creating excess strain on the bearing assembly. Maintaining this pressure helps to ensure the longevity and reliability of the bearing, as it creates a positive pressure condition that can effectively repel external contaminants while allowing for necessary operation without introducing interference or undue burden on the components involved.

Other psi ranges, such as 0 to 5 psi, may not provide sufficient protection against contaminants, while ranges above 10 psi could risk compromising the integrity of the sealing system. Thus, the choice of 5 to 10 psi is balanced for optimal performance and protection of the bearings.
