  K190 Series Two-Piece Center Bonded Vibro-Insulators®

 

 The K190 Series Two-Piece Center bonded Mounts are designed for heavy duty applications where there are dynamic forces in mutiple directions.  These two-piece mounts are installed through a mounting hole in a support structure.  The mounts are fail-safe when used with snubbing washers (not supplied).  The  K190 Series Vibro-Insulators isolate in all directions including the rebound direction.  The Two-Piece Center Bonded Mounts are also known as Universal Mounts, Ring & Bushing Mounts, and Versa Mounts.

 

 Features and Benefits:

  • Low cost and easy installation
  • Long life and low maintenance
  • The K190 Seies and the K20 Series have an interlocking metal fail-safe design when sunubbing washers (not supplied) are used
  • For effective multi-directional use. Loads best suited for use in the axial direction
  • Axial loads from 45 (20.4 KG) to 1630 (739 KG) pounds
  • Radial loads from 35 (15.9 KG) to 620 (281 KG) pounds
  • Accommodates 5/16" to 5/8" English and M8 to M16 Metric hardware
  • Available in 30, 40, 50, 60, and 70 Durometer Shore A
  • Available in the Natural Rubber, Neoprene, and Nitrile (Buna-N) elastomers
  • The K190-1 Series (K1901A41 thru K1901A73) does not have radial load specifications
  • 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:

Compressors, raditors, motors, blowers, panels, fans, fuel tanks, pumps and centrifuges, gen sets, HVAC equipment, military vehicles, rail, off highway equipment, trucking, farm equipment, lawn and garden equipment

 

Environmental Data:

  • All static load test data for the K190 Series 2-Piece Center Bonded Vibro-Insulator® Mounts is based on Neoprene. 
  •  10:1 Transmissibility at resonance.

 

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.
