 K25 Series Vibro-Insulators® Nut Cup Style

 

The K25 Series Nut Cups are ideal for low frequency vibrations.  The mounts offer excellent control against damaging vibration.

The K25 Series Nut Cup Series is also known as dish end plate/plate Mounts, and flex bolt sandwich mounts.

 

Features and Benefits:

  • Competitive pricing
  • Easy to install with no maintenance
  • Four sizes available K23, K24, K25, and K26
  • Compressive loads ranging from 85 to 560 pounds
  • Available in 40, 50, 60, and 70, Durometer Shore A
  • Available in Neoprene, Natural Rubber, 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:

  • Compaction and construction equipment, all-terrain vehicles, off highway equipment, vibratory rollers, shipping containers, HVAC

Enviromental Data:

Natural Rubber (NR):

All static load test data for the Cylindrical 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° 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.
  • Cylindrical 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° 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.
