Rolling Diaphragm Seals Stay Strong Under Pressure
February 27, 2021
When pneumatic or hydraulic pistons repeatedly slide inside of cylinders, they rely on fluid power to transmit force. It’s no secret that the total force couldn’t be transmitted without a tight seal. But rough-and-tumble environments and heavy-duty applications can destroy most seals. And when designs require low friction, high cycling, or high fluid pressure, O-rings or die-cut seals simply don’t hold up. In these situations, rolling diaphragms are often the only option. Unfortunately engineers may not know the advantages of rolling diaphragm seals or be aware of precautions to take when designing hydraulic or pneumatic systems that use them.
