Abstract
A device for heating a cylindrical component of given diameter is disclosed. The device includes at least two heaters each delivering a stream of hot gas and emerging in an annular chamber. The inside diameter of the annular chamber is slightly greater than the diameter of the cylindrical component. The device may be used for heating a metal journal in which a bearing ring for an inter-shaft bearing in a double-body turbomachine is mounted.
