Ribbed Vibration-Damping Grommets


Style 1	Style 2	Style 3

The ribs flex to absorb slow, rumbling vibrations better than smooth rubber grommets. Press into a hole to protect fine-tuned equipment from the vibration of nearby traffic and heavy machinery.

TPR Rubber—The choice for outdoor use, these mounts protect precision bearings and other fine-tuned parts from vibration through a bad storm or deep freeze.

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.

Multipurpose Neoprene—Resist wear and tear well enough for most applications. They are UV resistant and won't break down when exposed to oil, grease, and gasoline, so they're a good choice for motors and pumps.

TPR Rubber—The choice for outdoor use, these mounts protect precision bearings and other fine-tuned parts from vibration through a bad storm or deep freeze.

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.

TPR Rubber—The choice for outdoor use, these mounts protect precision bearings and other fine-tuned parts from vibration through a bad storm or deep freeze.

Chemical-Resistant PVC—Keep their flexibility when exposed to coatings, lubricants, and cleaning agents, such as the sodium hydroxide used in detergents.
