Bellows Coupling Replaces Gearbox In Cryogenic Apps

Gearboxes used in rotary drive systems operating near absolute zero temperatures, are often adversely affected by the extreme temperatures of a cryogenic environment. The most common failures are the result of differential thermal expansion which can cause the gears to uncouple. To solve the problem, nickel bellows can reliably replace the angled gearbox found in cryogenic projects and applications. The bellows generate less heat and shrink less than gears at milli-Kelvin temperatures, resulting in longer and more reliable operation. Servometer’s bellows employ a unique electroforming process that involves building thin metal layers onto precision machined mandrels. For more details, visit
