With their unique principles and construction, these multipurpose, versatile shock absorbers simultaneously combine the functions of spring, damper, and bearing in one unit. They are constructed of metal inner and outer shells and a cylindrical column of rubber. The cylindrical rubber is press-fitted into the inner and outer shells, which have a displacement of 45°. This suspension unit is the basic component for tensioners, rocking mounts, anti-vibration mounts, and suspension units for all manner of industrial machinery.
