ABSTRACT:
The invention relates to a bearing assembly adapted to be connected to a damper blade, and particularly a damper blade intended to be disposed within the duct of an air conduit used in a heating or cooling system. The assembly is characterized in that the bearing pin is supplied in a first position, from which it may be partially retracted, and after installation may be shifted to an extended position from which, if necessary, it may likewise be retracted, making it particularly suitable for installations wherein the duct interior is provided with an insulating lining.
