Roller bearing having a forcible lubrication functionToshio Suzuki
A roller bearing having a forcible lubrication function comprises an outer race provided with a radial rib directed inwardly. The bearing has a cage provided with a circular ring portion situated axially outwardly of the rib of the outer race to overlap the rib with a desired clearance to ...
“bearing” to the known position of the beacon. Direction finders consist essentially of a rectangularloop antennawired so as to send the difference in signals in the opposite, vertical sides of the loop to a “receiver.” This difference is zero when the sides of the loop are the same ...

At the same time, grease must be able to flow into the bearing through grease guns and from spot to spot in the lubricated machinery as needed, but must not add significantly to the power required to operate the machine, particularly at startup. (Boehringer 1992)...
The primary criterion for selecting an oil viscosity grade is the lowest temperature the oil will experience while in the engine oil sump. Bearing problems can be caused by the lack of lubrication during the cranking and start up of a cold engine when the oil being used is too viscous to ...
