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… WebTypical labyrinth clearances are in the range of 0.001” to .002” radial per inch of shaft diameter. They do not provide as effective a seal as Carbon rings but have a pressure drop limit of 4 to 6 times Carbon. In higher pressure differential applications, one will normally find stepped or high-low type labyrinth seals as shown in figure 5.

WebA labyrinth seal is essentially a series of annular orifices utilized to seal a region of high pressure from a region of low pressure. These are "clearance seals" and as such, leak.
