Trunnion is a type of gasket that is used to seal the joint between two trunnions. They are cylindrical shafts that support a rotating object, such as a drum or rotor. They are used to prevent fluids or gases from leaking through the joint between the trunnions.
They are typically made of a soft, compressible material, such as rubber, cork, or fiber. This material allows the gasket to conform to the uneven surfaces of the trunnions and create a watertight seal.
They are used in a wide variety of applications, including:
- Hydraulic cylinders
- Pneumatic actuators
