HA-S heavy duty anti-vibration hangers incorporate steel housing with the bases two sides bent down which increases rigidity of the housing and eliminates bending of the bottom plate under heavy load. Elastomer cups at the base and top of the spring have vulcanized steel washers which provide uniform load distribution on the bottom plate of steel housing. These cups reduce the transfer of vibrations and noise. Springs are color-coded and easily replaceable. All hangers elements are safe at solid load. All springs at maximum load have 50% additional travel to solid load. Hanger design allows for angular misalignment of 15 degrees.
