Can a bearing that has been hot-mounted be used again after it is removed?

Bearing model 22320 BM C4/W33, hot-mounted; can it still be used after removal?
It depends on how you take it down
The clearance of the bearing is within the standard when it remains assembled, and there is no noise during operation; special tools are used for disassembly. After removal, check the bearing for wear or pitting; if there is none, it can be reinstalled.
Strictly speaking, a assembled bearing is no longer usable; but if one has to make do, it’s not entirely impossible...
It depends on how you disassemble it, as well as the circumstances of the disassembly.
It’s better not to use it; if you do, check for signs of wear.
It was removed using a hydraulic ram, with no further heating. But it is still quite difficult to disassemble.
Hello! If the outer ring of the bearing is under stress during removal using a hydraulic ram, it will cause damage to the bearing.
Thank you very much. Since the bearing is quite large, force can only be applied to the outer ring during disassembly.
Another factor to consider is the requirements of the equipment; with bearings of this size, it’s safer to replace them with new ones
