The ROSTA oscillating mountings type AR are maintenance-free elastic joints used for the same purposes as our other oscillating mounting types AU, AS or AD. The distance between the centres can be freely chosen. The commercial circular tube (connection between the two elements) must be supplied by the customer. The inner square profile is frictionally engaged to the machine frame, analogously to type AS-C and AD-C.

The housing of mounting type AR is made of cast aluminium, the core is made of aluminium profile.
