Checking Shaft Sleeve Bearing
●As the shaft sleeve bearing error is very small,
generally it is unable to measure the clearance.
Remark
○Do not remove any bearing for check, because the
bearing must be replaced with one after removal.
●If it needs to check whether there is an axial clearance
in the bearing, it is jammed or blocked during the
rotation, please rotate each bearing in the hub back and
forth [A]!
★
If the bearing cannot rotate smoothly, please replace
the bearing!
Lubrication of Shaft Sleeve Bearing
●Add high-quality bearing grease to bearing. Rotate
the bearing for several times by hands to ensure that
the grease distribution in the bearing is uniform.
