labyrinth seal

Because these labyrinth seals are non-contact, they do not wear out.

The drum is sealed to its feed and discharge casings by labyrinth seals.

Turbocharger bearing failures, caused by exhaust gases leaking through the labyrinth seals.

Labyrinth seal. 3 Microns Max. spindle nose run out.

Non-contact, non wearing labyrinth seals prevent bearing lubricant entering the compression chamber.

A labyrinth seal is a type of mechanical seal that provides a tortuous path to help prevent leakage.

On the drive side the labyrinth seal can be located between the two bearings, the slotted carrier doubling as the bearing spacer.

NTN's unique inner ring seal groove and seal lip create a labyrinth seal for added protection.

The turbine blades expanded, however, contacting the honeycomb labyrinth seals and allowing the metal to scrape together when the engine overheated, with zero core rotation.

Options include a centrifugal liquid ring seal and a non-contacting inert gas purged labyrinth seal that eliminates leakage.

Cast steel bearing housings with heavy duty spherical roller bearings are bolted at both ends of the tube and protected from dirt and water with labyrinth seals.

All bearings and labyrinth seal chambers are completely shop filled with a lithium base grease, specially formulated to minimise roller drag and give maximum resistance to water wash out.

Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on other non-rotating shafts.

Problems with inward air leakage were expected with the joints between boilers and preheaters; these were built as spherical joints with labyrinth seals and leakage proved negligible.

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 difficult path to escape.

Many components like bottom brackets are fully sealed units requiring no maintenance for the life of the bearing in them, while close-fitting labyrinth seals protect the bearings of any well designed hubs from water and grit penetration.

Pipes may also be threaded with cylindrical threaded sections, in which case the threads do not themselves provide any sealing function other than some labyrinth seal effect, which may not be enough to satisfy either functional or code requirements.

Nothing was said, and yet much evidently was communicated, because scribes stationed along the row constantly scribbled deeds of sale that were validated by thumb-chops in green ink, and frantic clerks affixed tags stamped with the labyrinth seal of the Pontifex to the haunches of one beast after another.
