Heating in the bearings problem

Popular conditions, rolling bearing grease fill volume, always beyond the practice of intervening directly in the lubrication needs, full frame and bearing cover the cavity, and rolling the perimeter to form a contour. In this process, because of excess grease resistance, bearing temperature rise quickly. Although most of the excess grease in the early work that is crowding out and squeezed Raceway accessories grease is still likely to be migrated between roll shift rolling into the road.
Each type of unloading bearing, with a unique design. Regardless of the type of storage must be extra cautious, the bearing must be removed. When working, it may damage the bearings and shaft or housing, requiring expensive repairs. Remove the smaller camps, to help drivers, and others. Close consultation, or press, or there is a wave of locked, rather than by mechanical removal puller, bearing inner ring can be heated to reduce mobile. Can be used to heat lamps or other heating devices. If a torch change output of steel and bearings must be discarded. In some special operating conditions, longer life expectancy, especially under light-load conditions, in a traditional computing. This special operating conditions, if the track (track and rolling) separated by an efficient lubricating film reducing pollutants can result in surface damage. In fact, in ideal conditions, the so-called permanent storage life is possible.
The early stages of running these bearings, most of the grease quickly (less than a minute) out of raceways, are accumulated in the grease in the bearing migration into reincarnation, little being discharged one after another. When the bearing temperature continues to rise, up until all excess grease is discharged, may be called grease, walk-in-phase, based on the quality of lubricating grease in the bearing structure, elements such as padding, this period of time may last a dozen minutes, and even a few hours.
