Bearing race wear issue
Thread Content
Gurus, let’s talk about the issue of bearings running loose! ! !
Running the inner sleeve and running the outer sleeve are both fault phenomena that occur after bearings are installed and in use. Running in the inner ring usually refers to a situation where there is a gap between the inner circle of the bearing and the shaft, resulting in rotation that is not synchronized with that of the shaft. The term \"running on the outer ring\" usually refers to a situation where the clearance between the outer circle of the bearing and the bearing housing is too large, causing the outer ring to slip within the bearing housing and rotate along with the shaft.
The issue with the inner ring moving is mainly due to an inappropriate selection during assembly, which causes the bearing’s inner ring to fit tightly around the shaft”； Running on the outer ring means relative movement between the bearing’s outer ring and the bearing housing; friction marks can be seen on the end caps after disassembly. :D
Running on the outer track and running on the inner track are mainly due to coordination issues
I’ve seen ones that run on the outer rim and rub against the outer end cap. I’ve never seen anyone run on the inner track and eat the axle.
The situation of internal running rings is indeed not common, as a small amount of interference during assembly makes it easy to detect
