ABSTRACT:
The present invention relates to an alarm system suitable for use in warning of overheating in rotatable bearings 4 having first and second bearing portions. The alarm system comprises an alarm signal generator means having a thermally activated engagement element 8 on a first bearing portion or body 6 connected thereto. The element 8 is in thermal connection with the bearing 4 and is formed and arranged so as to be driven from a first primed retracted position into a second deployed extended alarm position upon reaching a predetermined temperature. In the alarm position the element 8 contacts an engaging portion 12 on the second bearing portion so as to produce a distinctive alarm signal indicating that said bearing 4 has exceeded the predetermined temperature.
