Abstract: Described is a device (10) for monitoring bearing performance in apparatus having an aperture sized and configured to receive a grease fitting. The device includes temperature sensing components (34) or vibration sensing components (36), or both, to enable detection of impending bearing failure, and is adapted to either replace or supplement conventional grease fittings (28). The device is configured so as to cooperate with bearings housings of widely divergent dimensions, and in each case to permit adjustment of the device, including the sensing components thereof, to place it in very close proximity to the bearing.

Abstract: Devices for monitoring bearing performance in apparatus having an aperture sized and configured to receive a grease fitting. The devices comprise a temperature sensor or a vibration sensor, or both, to enable detection of impending bearing failure, and further comprise rigidly attached electronic components which amplify signals generated by the temperature sensor and/or vibration sensor. The devices may be adapted to either replace or supplement conventional grease fittings, and enable the transmission of electronic signals which may be used for constant monitoring of critical equipment. Bearing housings which incorporate these features, as well as subassemblies and related methods, are also described.

Abstract: A armored light fixture which comprises an armored housing which defines an upper passageway through which light may pass, at least one lamp disposed within the armored housing, at least one reflector structure which is adjustable in position and which is disposed above the armored housing to enable the adjustable reflection of light which passes through the upper passageway of the armored housing.
