Rosta ab and ab-d range of spring mounts are ideal for the modern processing factory. These spring mounts are used with free vibrating equipment driven by vibration motors or with crank driven equipment. The advantage of these mounts and linkages are: noise free working without metal-to-metal contact; high vibration isolation; ability to handle large shock loads; robust, maintenance free construction; tear free design ensures total safety of equipment even in case of any disaster; long life of 3 to 6 years ensures minimum down time; vast range of capacities from 300 n to 16000 n per mount offered; stainless steel versions offered for the food industry; and controlled start and stopping ensures minimum transfer of residual forces to platforms. Retrofitting of existing conveyors working with metal springs is possible.
