WebLabyrinth seals work by throttling the flow through successive openings in series. In each throttle, static pressure difference accelerares the flow and some of the kinetic eneergy associated with the flow is dissipated by turbulence induced by the intense shear stress and eddy motion in the next chamber. WebThese seals have a metal case that creates a tight seal when mating with smooth surfaces. Spring-Loaded Rotary Shaft Seals Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft.
