Welded Metal Bellow Benefits:

Edge welded bellows are ideally suited for high cycle life applications requiring stroke in a constrained envelope.

Stroke Comparison of Edge Welded Bellows:

Flexibility characteristics of an Edge Welded Bellow:

Flexibility

• Edge welded bellows are capable of softer spring rate
• Axial, angular and radial

How Edge Welded Metal Bellows are manufactured:

Welded diaphragm metal bellows are composed of two contoured diaphragms – each constructed from thin stainless steel – are welded at the inside diameter to form a convolution. Capsules are formed when convolutions are stacked on a horizontal arbor and welded at the outside diameter.

Edge Welded Metal Bellows Terminology:

Types of Edge Welded Metal Bellows:

Resting Ripple Bellows:

Most welded diaphragm metal bellows have a nested ripple diaphragm configuration that provides maximum stroke, minimum stress, superior flexibility, and full nesting when collapsed or compressed.

• Long Stroke Capability
• Compact Nested Length
• Good Linearity
• Moderate Pressure Capability

Single Sweep Bellows:

Customized bellows, including those with flat plate, single sweep, and torus contours are available for special applications.

• Good Pressure Capability
• Good Stroke Capability
• Compact Nested Length
• Good Linearity
