Single Male Vibro-Isolator® Bumpers

 

Male conical bumpers and feet have a machined insert that is both chemically and mechanically bonded. These bumpers are highly durable at extreme temperatures. They can be used in thousands of applications.

 

Features and Benefits:

  • Easy to install and little maintenance
  • Low cost
  • Excellent skid resitenance
  • Highly durable
  • 50 & 60 Durometer Shore A elastomers offer an excellent rebound
  • Natural Rubber (-40° F to 155°F) and Nitrile (-40° F to 300° F) elastomers have excellent resistance to extreme tempatures
  • 2-D PDF prints are available for each mount
  • 2-D DWG, 3-D IGES, and 3-D SolidWorks are available upon request
  • Made in the USA

 

Environmental Data:

  • All static load test data for Bumpers and Feet Vibro-Isolator® Mounts is based on Natural Rubber.
  • Natural Rubber operating temperatures should not exceed 155° F.
  • Natural Rubber is not recommended from exposure to oil, gasolene, ozone, and sunlight.
  • Other elastomers such as Neoprene and Nitrile (Buna-N) are available upon request.

 

Natural Rubber (NR):

All static load test data for Bumpers and Feet Vibro-Isolators® Mounts is based on Natural Rubber.

Advantages:  Outstanding resilience; high tensile strength; superior resistance to tear and abasion; excellent rebound elasticity (snap); good flexibility at low temperatures (-40° to 155° F).

Limitations:  Poor resistance to heat, ozone, and sunlight; very little resistance to oil gasoline, and hydrocarbon solvents.

  • Operating temperatures should not exceed 155° F.
  • Natural Rubber is not recommended from exposure to oil, gasoline, ozone sunlight.

 

Neoprene (CR):

Advantages:  Good inherent flame resistance; moderate resistance to oil and gasoline; very good resistance to weather, ozone, and natural aging; good resistance to flex cracking; very good resistance to alkalis and acids.

Limitations:  Poor to fair resistance aromatic and oxygenated solvents; limited flexibility at low temperatures (10° to 180° F).

Nitrile (Buna-N):

Advantages:  Very good resistance to oil and gasoline; superior resistance to petroleum-based hydraulic fluids; wide range of service temperatures (-65° to 300° F); good resistance to hydrocarbon solvents; very good resistance to alkalis and acids.

Limitations:  Inferior resistance to ozone, sunlight, and natural aging; poor resistance to oxygenated solvents.
