K22 Series Vibro-Insulators® Center Bonded Bushings

 

The K22 and K222 are one piece center bonded bushings that are designed to be compressed and fitted into a socket with a 2.22" diameter and a 1.88" length. The radial load deflections specified were tested in this manner. The K22 Series Bushings provide rotational freedom while utilizing a soft torsional spring rate.

 

Features and Benefits:

  • Low Cost
  • Easy to install
  • Minimual maintenance
  • Available in 2 sizes K22 (small) K222 (large)
  • Produced with high strength Natural Rubber
  • Available in 40, 50, 60, 70, and 80 Durometer Shore A
  • Other elastomers available
  • Metals are protected with zinc phosphate
  • 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:

Typical applications include: wheels, vibratory feeders, construction equipment, farm equipment, machinery

 

  • All static load test data for the K22 Series Center Bonded Socket Style Vibro-Insulator® Mounts is based on Natural Rubber.
  • Operating temperatures should not exceed 155° F.
  • Natural Rubber is not recommended from exposure to oil, gasoline, ozone, and sunlight.

 

Natural Rubber (NR):

All static load test data for the Center Bonded Socket Style 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° 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.
  • 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° 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.
