WebJun 25, 2001 · The standard seal for SAF and SAFD pillow blocks is the LER aluminum, labyrinth design. This noncontact seal doesn’t generate heat on the shaft and can handle high speeds. It is limited in its ability to seal in a dirty environment. An O-ring in the inner bore is particularly useful when using oil because it seals along the shaft. A labyrinth seal is a type of mechanical seal that provides a tortuous path to help prevent leakage. An example of such a seal is sometimes found within an axle's bearing to help prevent the leakage of the oil lubricating the bearing. A labyrinth seal may be composed of many grooves that press tightly inside another axle, or inside a hole, so that the fluid has to pass through a long and d…
