High load capacity, stability, and the ability to be installed at any mounting angle make them ideal for a wide variety of applications, including vehicle cabs; truck, bus and marine engines; generators; air conditioning units; motors and electronic equipment.. You can install them at any convenient mounting angle thanks to their "shouldered" core design that makes optimum use of the neoprene elastomer shear and compressive properties. They offer a fail-safe installation when the proper snubbing washers are used. Oil, fuel and solvent-resistant neoprene-with a temperature range of -20 to +180F- provides isolation in all planes, regardless of the direction of the exciting forces. At maximum load, the natural frequency of these mounts is about 8.5 Hz. providing effective isolation from disturbing frequencies of 12 Hz. and above.
