The range of conical mountings is designed especially with medium speed engines in mind. The conical design provides high deflection and load capacity combined with long service life. Available with or without interleaf, the sandwich mountings are produced in a range of rubber mixes and sizes, to meet stiffness tolerances. This type of mounting can also be used in earthquake areas. Selection of the rubber hardness and the position of the sandwich mountings is done based on the weight of the installation and the disturbing frequencies that have to be isolated. All mountings are individually tested and selected on stiffness.
