Dome Style Vibro-Insulators® Fail-Safe Compression Mounts

 

On the underside of the K61, K62S, and K62C Vibro-Insulator® Dome Mounts is an elastomeric molded socket that is adapted to accept a standard 1/2" (K61), 5/8" (K62S) and 3/4" Heavy Duty (K62C) hex head nut or bolt. There are two retaining ears located in the center insert which are designed to be bent over the mounting bolt or nut. The interlocking metal design promotes a fail-safe mount.

 

Features and Benefits:

  • Easy installation
  • Low cost
  • Mounting applications include equipment mounted to either a support structure,  or panel or wall
  • Horizonal or vertical loads
  • No maintenance and long service life
  • Isolates distriburing frequencies as low as 1800 RPM
  • Encapsulated inner metal providing interlocking metal protection
  • Available in 30, 40, 50, 60 & 70 Durometer Shore A
  • Standard elastomer is Neoprene. Other elastomers available upon request
  • Made in the USA

 

Applications:

  • Motors, generators, and compressors
  • HVAC equipment
  • Chemical and food processing equipment
  • Centrifuges and pumps
  • Highway and off-highway machinery
  • Trucks, buses, lifts, and rail transportation
  • Marine equipment and ATV's
  • Fans, blowers, and portable power equipment
  • Seismic protection in earthquake zones
  • Wind energy

 

Environmental Data: 

  • All static load test data for the K61 & K62 Style Vibro-Insulator® Mounts is based on Neoprene.
  • Structure made of corrosion resistant carbon steel plated with Yellow Zinc Dichromate.

 

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, and 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.
