Ribbed Vibration-Damping Bushings
Ribbed bushings are more flexible than our smooth vibration-damping bushings, so they're easier to install. Use them to damp vibration and reduce shock inside motors, fans, blowers, actuators, circuit boards, and other electronic equipment.
Use Vibration-Damping Washers to fill space between the bushing and the surface of your equipment.
