Note:If the bearing requires high speed or must bear high load, the transition fit between the bearing and the shaft should be used.

Pillow Block Ball Bearings Note:Mounted spherical ball bearings used for industrial fans and blowers, which require high speeds. At this time, the coordination between the outer spherical ball bearing and the shaft requires higher accuracy. Generally, the h5 or j5 level tolerance is used for the shaft.
