Zusammenfassung:	A bearing overheat indicating apparatus comprises a pin of meltable material 27 which secures weight 25 to arm 28 within a rotating portion of a shaft 19 adjacent, and supported by the bearing, and upon bearing overheat occurring the meltable material 27 melts causing displacement of the weight 25 which causes an out of balance of the shaft which is detected by a vibration detector. in an alternative apparatus a tube 30 secured to the shaft, contains, at an enlarged portion 31, a relatively dense liquid e.g. mercury which is retained by plugs of meltable material, or a meltable solid.
