A continuous hot dipping apparatus comprising:
- a tank including a bath of molten metal inside;
- a sink roll;
- and
- at least one guide roll;
- at least one of the sink roll and the at least one guide roll defining a roll being supported by a bearing, the bearing being composed of at least a connection part and a bushing, the connection part including three successive parts:
- a first part connecting with the bushing,
- a second part comprising at least one fastener attached to a side of the roll, and
- a third part having a parallelepiped section with curved angles, the third part being inserted inside the roll,
- the connection part being made of a material having a higher thermal dilatation coefficient than the roll, the coefficient being chosen so that the third part and the roll are pressfitted through thermal dilatation when in the bath of molten metal.
