WebJul 23, 2007 · One of the tests we can run on the dyno is called a 'seal drag' test. This test checks the drag of all the components in a fork or shock that contribute to stiction, inclucing the seal, bushing and piston. Obviously, forks have a greater amount of surface area and are more likely to bind than the shock, and reduced seal drag is very important.

Like deadband, stiction causes a valve not to move, but instead “stick” in a particular position. Moving the valve requires additional force, which, also like deadband, can lead to the valve overshooting its position and the process overshooting its setpoint. rcw formatting
