Isolation washers and Fabreeka bushings are used to eliminate metal-to-metal contact and break the vibration or shock transmission path. For example, the contact between a machine base and an anchor bolt as shown.
Washers & bushings are typically used in conjunction with Fabreeka pads or Fabcel pads where the reduction of impact shock or isolation of transmitted vibration is required.
Isolation washers made from Fabreeka pad material can ultimately withstand loads up to 12,000 psi when used for “uplift” or rebound shock.
Isolation washers and bushings complete the isolation solution by eliminating the vibration and shock transmission path.
Washers can be die cut to any outside/inside diameter required for your application.
Isolation washers are manufactured to interface with standard bolt/washer sizes from 3/16″ to 3″.
What are the manufacturing tolerances of the OD/ID? Standard OD/ID tolerances for washers made of Fabreeka pad material are +/- 1/16″. Tighter tolerances may be possible. Please contact Fabreeka’s Engineering department at 1-800-322-7352 or firstname.lastname@example.org to discuss the tolerances for your application, or for material tolerances other than Fabreeka pad.
Do I use the standard fastener torque for the hardware size I am using with my isolation washers? No, Please use Fabreeka’s published torque specification when using Fabreeka material for isolation washers.
When using Fabcel or other materials for isolation washers, please consult Fabreeka’s Engineering department at 1-800-322-7352 or email@example.com for proper torque information.
