• These data were obtained with 1.2mm -thick PCB sandwiched for type A, 1.5mm for type B, and 1.0mm for type S.
• Recommended frequency depends on loads.
• Since this product is very soft and easily damaged, please handle with care.

Notes:

  • 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 can be removed for use.
