Choose the right vibration-damping mounts to protect equipment from damage and reduce noise.
Vibration-Damping Bushings
 |  |  |
Style 2 | Style 3 | Style 4 |
These bushings have a taller profile than vibration-damping grommets, so they can be used in thicker panels. With only one rim, they're also easier to install. They isolate vibration around motors, fans, blowers, and actuators to extend part life and minimize downtime.
Chemical-Resistant PVC—Keep their flexibility when exposed to coatings, lubricants, and cleaning agents, such as the sodium hydroxide used in detergents.

Vibration-Damping Grommets
 |  |
Style 1 | Style 2 |
Press these slim, flexible grommets into a hole when space is too tight for a sandwich mount. They block vibration around sensors and other parts you count on for precise movements, strong signals, and accurate readings. The rubber stem and two flanges line the inside and both faces of a hole so no vibration can flow between the fasteners and mounting surface.
Chemical-Resistant PVC—Keep their flexibility when exposed to coatings, lubricants, and cleaning agents, such as the sodium hydroxide used in detergents.

Ribbed Vibration-Damping Washers
 |
These washers add a rubber buffer between fasteners and mounting surfaces so vibration doesn't flow through and cause damage. They're often used to mount sensors, circuit boards, and other sensitive electronic components. To absorb more vibration, stack two washers together.
Chemical-Resistant PVC—Keep their flexibility when exposed to coatings, lubricants, and cleaning agents, such as the sodium hydroxide used in detergents.
Ribbed Vibration-Damping Bushings
 |
Style 1 |
The ribs flex to absorb slow, rumbling vibrations better than smooth rubber bushings. Install these bushings around shafts, large fans, and other slow-rotating components to extend part life and minimize downtime. Pair a ribbed vibration-damping washer with a bushing to absorb more vibration.
