Dynamic spring constant of vibration control rubber is 1.3 times higher than that of a static one.
Note: For choosing PTH, detailed calculation will be needed in centroid position or tension by hanging bolts when using air conditioning device. Please ask for more detail to our sales representative.

Handling instructions
  • The product has to be protected from any damage.
  • Please note that the product must be avoided adhesion such as strong acid, strong alkali, organic solvent, fat and oil.
  • Rubber needs to be attached as equalized loading toward the vertical and compression direction.
  • Please make sure to use the device within a given load range.
  • The product must be protected from spark like welding.
  • The product must be attached with double nut.
  • When supporting pipes, pulps, flange and the other weights need to be considered for calculation.
  • Product should be chosen after calculating the load weight to the each hanging bolt when the multiple pipes are hung all together.
  • The impact or excessive force could lead to release the parts from assembled product.
