The CLU Eurobelt retainer rings guarantee the fastening of the central sprocket on both drive and idle shafts.

The belt can expand or contract due to the temperature.

The drive system of modular belts requires the central sprocket not to move axially both in the drive and the idle shafts.

The rest of sprockets can slide freely on the shaft adapting to the possible changes of the belt, so that the correct position of the teeth is guaranteed.
