K69 & K695 Series Fail-Safe Vibro-Isolator® Compression Mounts

 

 In addition to the 1st and 2nd generation K69 & K695 Series, Karman Rubber now offers the 3rd generation K69 Series Compression Fail-safe Mounts. The largest selection of compression style fail-safe designed mounts available anywhere.

 

 

K69 & K695 Series Features and Benefits:

  • Low Cost.
  • Ease of installation.
  • Rated for higher loads due to the interlocking metal design.
  • Seismic rating of 1g (acceleration of gravity).
  • Seismic protection in earthquake zones. See below for g-force ratings.
  • Available in English and Metric hardware.
  • Six sizes with 5 load ranges for each size.
  • Static compression loads range from 160 to 750 pounds.
  • Fail-safe patented designs with interlocking metals.
  • No need for snubbing washers.
  • Excellent performance with one, two, three, four and five cylinder engines.
  • Suited for both high and Low disturbing frequency applications.
  • All directional mounts can be used in shear, tension, and compression applications.
  • Suited for low mounting applications.
  • The K69 and K695 are the first and second generation series.
  • Made in the USA.

 

K69 and K695 Series 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.

 

K69 & K695 Series Material Data:

  • The Neoprene elastomer is standard in 30, 40, 50, 60, & 70 Durometer Shore A.
  • Operating temperature range (10° F to 180° F).
  • Ozone resistant
  • Oil, gasoline and solvent resistant.
  • Flame resistant
  • Structure made of corrosion resistant carbon steel.

 

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.
