In this way, the matching of the screw and barrel diameterclearance, with the gradual wear and tear of the a little bit more.
这样,螺杆与机筒的配合直径间隙,随着二者的逐渐磨损而一点点加大。
2
The average radial clearance, body clearancediameter of the external channels and rolling direction.
平均径向间隙,外部渠道和全身清除直径轧制方向。
3
For needle roller bearings without inner ring, a suitable internal clearance is achieved by selecting the appropriate tolerance for the raceway diameter.
