Metal bellows have long been a key component in demanding sensing and sealing applications. In fact, they’ve become so familiar that many engineers now think of bellows as generic items: Just specify a few key dimensions, pick a metal alloy and you’re good to go.

The reality, however, is that not all bellows technologies are created equal. Different manufacturing methods and material grades can have profound effects on how metal bellows will perform in terms of their stroke, pressure capabilities, spring rate and temperature response.

Manufacturing methods and materials will also determine how long your bellows will last in the field. The wrong bellows may work for a short time but not achieve your expected lifecycle.

Our latest white paper takes a close look at the different aspects of metal bellows–including design considerations, manufacturing methods and materials–to help you pick the right one for your application.
