When the sliding bearing works, does the Bush not rotate and the journal rotates?
That's the general rule. But there is also the axle neck does not rotate, bearing change.
Generally, the Bush and the bearing seat are relatively fixed, and the shaft rotates; also, the shaft is fixed and the Bush rotates.In fact, it is essentially the same, that is, that one component rotates relative to the other.
Yes, usually when high speed runs, the oil will form an oil wedge between the shaft and the Bush, not directly between the two.
