Since the needle roller bearing has a variety of different devices, nature also have different disassembly method, which compare with common include tapping method, thermal method, four methods of push and pull.
Every a way to remove the needle roller bearing steps is different, how to control them one by one?
First there is the needle roller bearing tapping method, general conditions, remove the needle roller bearing by tapping method, the main effect on the bearing inner ring, tapping force rather than add in rolling element bearings and insist on the shelf.
That is to say, the remove method is the key to get the main point, the position of the block placed to the right.
This way is simple execution compare, but have a bit easy to damage the bearing carelessly, so when removing the needle roller bearing must be especially careful in, don't be random percussion, so as to avoid the problem of no need.

Compared the above two kinds of sealed way, remove the needle roller bearing with push method match smoothly, it use the press to push the bearing, it won't for formation damage to the machine, needle roller bearing can stick to good integrity.
Then there is a kind of pull out method, using this way to remove the demand USES specially puller, simply choose to pull the handle, the bearing can be gradually pulled out.
Puller, of course, a reasonable choice is also very critical, otherwise how laborious also is unable to do it again.
