Male/Male Conical Vibro-Isolators®

 

Conical Vibro-Insulators® are designed to protect machinery and equipment from unwanted noise vibration and shock.  Their simple design allows these mounts to be used in a variety of applications. Designed for compressive loads Conical Mounts are not designed to be used in the tension mode.  Single male conical mounts are also used as bumpers and feet.

 

Features and Benefits:

  • Low cost
  • Easy to install and no maintenance required
  • Compression loads from 40 to 180 pounds
  • Compounds formulated for optimal chemical and mechanical elastomer-to-metal bonds
  • Available in Natural Rubber, Neoprene, and Nitrile (Buna-N)
  • Available in 30, 40, 50, 60, and 70 Durometer Shore A
  • Available with male/male, male/female, and single male hardware
  • Available in both English and Metric hardware
  • All inserts plated with yellow zinc dichromate
  • Metal inserts are hardened to Grade 5 Specifications
  • 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:

  • Motors, blowers, fans, HVAC, compressors, gensets, welders, panels, materials handling equipment, pumps, office equipment, medical devices, centerfuges, dryers, lawn and garden

 

 Environmental Data:

  • All static load test data for the Conical Vibro-Insulator® Mounts is based on Natural Rubber.
  • Operating temperatures for Natural Rubber should not exceed 155° F.
  • Natural Rubber is not recommended from exposure to oil, gasolene, ozone sunlight.  
  • Conical mounts are not recommended for use in the tension mode

 

Natural Rubber (NR)

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.
  • Conical style mounts are not recomened in tension applications.

 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 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.
