To select the best shock absorber for your application, you need to find the energy capacity your application requires. Use this formula to calculate the energy capacity required to stop a horizontal-moving load. For example, if you have a 250-lb. load moving at 25 inches per second, your calculation is (250 lbs. ÷ 772) × 25² = 202.4 in.-lbs. energy capacity.

Note: Choose a shock absorber with a higher energy capacity than you calculated. Factors such as driving force or an inclined surface will increase the energy capacity required.
