Square Vibro-Insulators®

 

 

Features and Benefits:

  • Low cost
  • Easy to install and no maintenance
  • Loads are in the compression mode
  • Compounds formulated for optimal chemical and mechanical elastomer-to-metal bonds
  • Plated with yellow Zinc Dichromate
  • Availabe in 4 sizes with load ranging from 2 pounds to 35 pounds
  • Available in Natural Rubber Neoprene and Nitrile (Buna-N)
  • 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

 

Applications:

  • Small motors, cameras, compressors, fans, electronic equipment, medial equipment, valves, small pumps, business machines

 

Environmental Data:

  • All static load test data for the Square Vibro-Insulator® Mounts is based on 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.
  • Square Mounts are not recommended for use in the tension mode.

 

Natural Rubber (NR)

All static load test data for the Square Vibro-Insulator® 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° F 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° F 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° F 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.
