Products Mounted Type(Insulators)

These simply designed insulators support the product and effectively isolate vibrations. Combining softness and durability, Alpha GEL shows exceptional damping functionality for low to high frequency vibrations, making it far superior to rubber.

Characteristics
Various insulators are available for loads from 2 to 300kg with 4 points of supports.
Ideal for low frequency and micro vibration due to the resonance point being set low.
※Pick the best fit for your application based on load, resonance point and available space.
Application Example
Alpha GEL vibration insulators also absorb vibrations in a low frequency area, where conventional rubber dampers are not effective.

Notes

Correct Use
❶ Even load
❷ Compressively suspended
Incorrect Use
❶ Uneven load
❷ Misaligned bolt hole
❸ Twist
❹ Tensile direction
❺ Shearing direction

※*Always use in compression.※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 metal. This could cause detachment of GEL from metal.
