Combination isolators provide the excellent shock absorbing properties of rubber in shear and compression with good dynamic cushioning under rugged operating conditions. These isolators are designed to be used as an assembly. The rebound unit limits the free movement of the equipment to some extent, but this restriction is very desirable in mobile installations. Care must be taken when installing to ensure that the nut is not drawn too tightly so as to avoid any excessive pre-loading of the isolator and rebound unit.
