In order to make the bearing work normally, under the condition of continuous operation, the bearing must bear a certain minimum load, that is, C/P<25. Otherwise, the wear will be aggravated due to insufficient lubrication and high-speed operation. All multi-row cylindrical roller bearings have a lubricating groove and a lubricating hole on the outer ring.
