When it comes to protecting machinery and critical components against large jolts and emergency stops, rubber bumpers and springs are ineffectual and hydraulic shocks are expensive. A low-cost, disposable alternative is Enidine Inc.'s one-shot shock, now being introduced in Europe. The shocks were designed primarily for use as a fail-safe device in high-speed servodrives, but can be used for other industrial machines as well. They are made of a noncorroding polymer and will last 10 years, despite exposure to temperatures ranging from -25 to 50C (-13 to 122F). Once the lightweight, crushable shock is used, it is thrown away and replaced.
