Rubber Bushings – Sleeves, Spacers & Vibration Isolation Bushings (All Sizes)

Shop rubber bushings — cylindrical rubber sleeves and spacers that cushion bolts, isolate vibration, protect wires passing through metal, and take up slack between a fastener and a hole. A rubber bushing works anywhere metal-on-metal contact would rattle, wear, or conduct vibration: equipment mounting points, machinery frames, panel pass-throughs, and light automotive or appliance repairs.

How to size a rubber bushing: match the inside diameter (ID) to your bolt or shaft, the outside diameter (OD) to the hole or clearance available, and pick thickness/length based on the gap you're filling. Thick-section neoprene washers and spacers (up to 1/2" thick) work as flat bushings under fasteners, while rubber grommets handle lined pass-through holes in sheet metal.

Common uses: vibration isolation on motor and equipment bolts, sleeve spacers for machinery, wire and cable protection through panels, anti-rattle isolation on brackets, and cushioned mounting for pumps, fans, and compressors. For complete stud-mounted isolation, see our rubber vibration isolator mounts. Material questions? Check the rubber material guide. Production quantities? Bulk pricing available.
