Laminar rings are metallic components which are used to create a labyrinth by combining multiple rings in a machined groove. The arrangement and orientation of the laminar rings is dictated by the application and the severity of the external environment.
Produced from metal, laminar rings are used as sealing elements in both rotating and static sealing applications, protecting sensitive components from contamination and abrasion. Each laminar seal ring or combination of rings generates an efficient labyrinth which makes them an ideal choice for applications which are sensitive to thermal gradients.
- Easily withstand high temperatures
- Higher corrosive atmospheres than other more standard elastomer solutions
- Capable of retaining grease
- Excludes high levels of external contamination
- Outstanding sealing characteristics
- Generate extremely low levels of friction
There are a standard range of metric and imperial laminar rings sizes available each with different material options to suit individual applications. Due to their compact design, laminar rings can be elegantly packaged into most applications either as part of the original design or to upgrade existing products in order to improve reliability and service life. In more arduous applications, it may be necessary to purge grease through the laminar ring system. In such cases, it is necessary to make subtle changes to the housing design to avoid any pressure build up.
Laminar rings can be used as primary seals in systems where the exclusion of external contamination is required to protect a more sensitive oil seal system. This approach can be used to greatly extend the life of mechanical equipment in question.
