αGEL Products Bush-Type（Gel Bushings）

These anti-vibration bushings are secured with screws. They are small, soft, and easily compressible, allowing for effective control of micro-vibrations experienced by light-weight PCBs.

Characteristics: ●Effective for minimizing horizontal drift, using a bolt running through the Gel Bushing.; ●Designed to dampen tiny to light loads and micro vibrations.; ●Available for loads from 0.2 to 32kg with 4 points of support.

Application Example: Alpha GEL isolators are ideal primarily for light-load items such as PCBs. Its softness and mechanically reinforced strength allow for a smaller build and ensure long-term high performance.

Notes

Drawing for installation

・Since this product is very soft and easily damaged, please handle with care.
・Tighten the bolt all the way to the collar.
・Usable bolts are M3 or smaller for Type-A, M4 or smaller for Type-B, and M3 or smaller for Type-S.
・Use a washer equal to or bigger than the diameter of the upper portion of GEL Bush.
・Collar inside the GEL Bush is removable. ※Data was obtained with 1.2mm-thick PCB for Type-A, 1.5mm for Type-B, and 1.0mm for Type-S.
※Recommended frequency depends on loads.
