Memo:
As there is no retainer ring for the inner ring of the bearing, the inner and outer rings can be installed separately. Its structure disables to limit the axial displacement of itself and its
shell and only enables to bear the radial load. Its ring is usually not reserved with
lubrication hole. If required by the client, the hole may be processed in the inner or outer
ring. After high-temperature tempering treatment of its components, the bearing can work
normally at about 300℃
