A roller bearing replacement device for replacement or exchange of a roller bearing of a roller hearth furnace includes a housing that can be sealed off against the external atmosphere with a sluice through which it is possible to access to a roller bearing of the roller hearth furnace that is to be demounted from inside the housing while excluding the environmental atmosphere, and at least one roller bearing handling device designed and constructed for demounting and installing roller bearings that is arranged in a moveable manner in the housing and can at least partly be moved out of the housing through the sluice. The sluice has a docking flange and a gas tightness monitoring arrangement, by means of which the gas-tightness of the docking connection on to the roller hearth furnace by the sluice can be monitored.
