Senior Aerospace Metal Bellows designs and manufactures a variety of bellows dynamic seals.These seals are ideal for high temperature applications where elastomeric seals break down.
These seals are commonly circular but can also be squares, rectangles, ovals or whatever shape will fit with the application.
Common materials of construction are stainless steel or high nickel alloys for higher temperature applications.
Typical applications include engine nacelle seals, firewall seal, fuel drain seal, and engine duct seals.
Bellows Mechanical Face Seals
Used as engine shaft seals or engine gearbox seals, the bellows type mechanical face seal offers advantages including:
All welded hermetic construction
Bellows replaces the secondary o-ring seal
Zero secondary leakage
Uniform (360°) face loading
No sticktion or hysteresis
Accurate and repeatable load at length
Longer axial stroke capability
Bellows versus wave spring
Suitable for extreme temperature environments
-65F to 900F
