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.
