Advanced Antivibration Components (New Hyde Park, NY) offers V11Z48MPSB Series air spring vibration mounts that feature vibration isolation of low-frequency machines. The air springs use elasticity of air as an isolator, which acts as a soft spring, eliminating moving parts. The mounts handle a range of loads by changing the inner air pressure. The metric isolators are suitable for oscillating conveyors, air compressors, water pumps, generators, and air blowers. They also can be used as actuators in tensioning devices. The bellows are made of synthetic rubber that incorporates a reinforced cord and wire. The clamping rings and upper and lower plates are made of stainless steel.
