Gels - Vibration Insulators

 

General Features of our Gel Products

Highly Durable - Our gels are highly resistant to ozone, UV rays, and chemicals, making them ideal for a large range of diverse applications.

Consistent Performance - Even in extreme conditions (-40°C to 200°C) the gels provide stable performance.

Safe - the gels are non-toxic, non-allergenic and emit no harmful gasses when burned.

 

 

  • Excellent vibration dampening qualities for loads 2Kg - 300Kg
  • Ideal for low frequency and micro vibration due to resonance point designed to be set low.
  • Pick the best fit for your application based on the load (weight). 
  • The published data are based on 4 points of support (usage).

Type SF (Rubber Coated)

  • For applications where a bottom plate is preferable and there is a need for damping
    heavy-load vibration.
  • Good for outdoor use in particular due to reinforced durability deriving from Gel wrapped by
    bellows-type EPDM rubber.
  • Stable performance in the -20°C to 90°C range.

Metal parts have a choice between 1 and 2.

  1. Upper bolt material : Iron with trivalent chromate plating
    Bottom plate material : Iron with trivalent chromate plating
  2. Upper bolt material : SUS304 / Bottom plate material : SUS304

 

  • The height of the insulator may vary as the GEL is compressed under load.
  • The direction of the slot on the head of stud is not controlled.
  • Do not remove the GEL burr around the edge of the metal. This could cause detachment of GEL from metal.
