The Dual 66 is recommended when the pin needs to be locked to the inner ring of a bearing to ensure that the joint only moves between the inner and outer ring of the bearing.

This solution consists of a pin with long tapered ends, two inner conical sleeves fitted on to the long tapered end of the pin, two outer conical sleeves fitted on top of the inner conical sleeves, fasteners for the inner conical sleeves and end-plates pushing on the outer conical sleeves.

The inner conical sleeve expand to form a zero tolerance connection in the inner bearing ring and the outer conical sleeve form a zero tolerance connection in the support bores.
