Labyrinth seal - Wikipedia

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 ...

What are labyrinth seals for bearings? Bearing Tips

16/07/2018  Labyrinth seals are a common type of mechanical seal used to prevent contamination within a bearing system’s design. Bearings are frequently used in locations with prolonged exposure to abrasive dust, dirt, debris, or mud. In these heavily contaminated environments, the bearings need protection from these external factors to operate reliably.

Labyrinth Seals Bearings, Chain and Power Transmission ...

LABYRINTH SEALS (LO) Labyrinth seals are made up of a single metal ring component that interconnects with the grooves in the housing to form a labyrinth gap. The inside diameter of the metal ring contains an O-ring that creates an interference fit with the shaft so that the ring will rotate with the shaft. Labyrinth seals can be used on high-speed applications and in moderately contaminated ...

Labyrinth Seals GMN Bearing USA

Labyrinth seals are usually the first barrier of protection and help prevent bearing failure. In complex sealing systems when a contact seal is required, using a non-contact labyrinth seal before the contact seal will boost the sealing protection and we definitely recommend doing this for harsh, dusty or contaminated environments.

Bearing seals - NSK Europe

Some types of seal do not come into contact with the shaft. These include oil groove seals, flingers and labyrinth seals, for example. As they have little running clearance, they usually have a sufficient sealing action. Centrifugal forces also help to prevent contaminant ingress and lubricant loss. 1. Gap seals Gap seals feature a thin cavity between the shaft and the housing and have ...

How does a labyrinth seal work? - AskingLot

26/01/2020  Labyrinth seals or glands are fitted to the shaft and casing to prevent the leakage of exhaust gas into the turbine end bearing, or to prevent oil being drawn into the compressor. To assist in the sealing effect, air from the compressor volute casing is led into a space within the gland.

How Labyrinth Seals Control Contaminant Ingression

All contaminants trying to enter the bearing housing must go through the seal’s maze (labyrinth) of turns and angles in order to reach the bearing. On the path through all of these turns, particles are constantly subjected to centrifugal forces due to the rotational motion of the shaft, and only a very small number make it through the entire length of the seal.

What is a Labyrinth Seal?

21/01/2021  A labyrinth seal is a seal which creates a complicated path for liquids to pass through, making it challenging for liquids to cross the barrier created by the seal because they have difficulty making their way all the way through the labyrinth. These types of seals are used in a variety of settings, and can be used on objects which rotate and otherwise move. In fact, movement can make the ...

02/12/2020  A labyrinth seal is a type of bearing isolator that combines elements of contact and non-contact seals in a single component. The idea of a labyrinth seal is to prevent leakage and contamination by creating a difficult path for both substances to follow. Labyrinth seals are composed of multiple pieces – one that remains stationary and another the rotates with the system. The two pieces ...

COMPARISON OF LEAKAGE BETWEEN A LABYRINTH SEAL AND

Labyrinth seals (LBS) are the most common and inexpensive seal type, albeit wearing out with operation thus penalizing performance and even affecting rotordynamic stability. Costlier brush seals (BS), common in gas and steam turbines, can reduce secondary flow leakage by 50% or more than with a similar size LB. Novel non-contact all metal compliant seals, such as the Hybrid Brush Seal (HBS ...
