Machinery Vibro-Isolators® Compression Mounts

 

The K3 & K4 Compression Mounts are designed for static load applications with low distributing frequencies (12 Hz).  The mounts will effectively control noise and vibration at 800 rpm. These mounts are well suited for heavy industrial machinery and equipment.

 

 Features and Benefits:

  • Low Cost
  • Easy installation
  • Wide load range from 700 to 5400 pounds of static compressive loads
  •  Available in 30, 40, 50, 60, 70, & 80 Durometer Shore A
  • Standard elastomer is Neoprene
  • Also available in Natural Rubber and Nitrile (Buna-N)
  • Availabe with 1/2-13 and 3/4-10 equipment taps
  • Excellent performance with one, two, three, four and five cylinder engines
  • High and Low frequency applications
  • K3 & K4 Mounts can be used in tandem
  • Suited for low mounting applications

 

Applications:

  • Motors, generators, and compressors
  • HVAC equipment
  • Chemical and food processing equipment
  • Centrifuges and pumps
  • Stationary blowers and fans. 
  • Made in the USA.

 

Material and Enviromental Data:

  • Structure made of corrosion resistant carbon steel plated with Yellow Zinc Dichromate.
  • All static load test data for the Machinery Compression Vibro-Insulator® Mounts is based on Neoprene.
  • Operating temperatures should not exceed 180° F. 
  • Other elastomers such as Natural Rubber and Nitrile (Buna-N) are available upon request.
  • Machinery Compression 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° 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.
