Fully loaded cylindrical roller bearings are designed to withstand heavy loads. Under the same width, compared with the traditional bearing with cage, this bearing has very high bearing capacity, small radial section, space saving, but the speed is relatively low. In order to make the bearing work normally, under the condition of continuous operation, the bearing must bear a certain * * * small 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.

Sl02 (nncl) series full loaded cylindrical roller bearings are non sealed bearings with no flange on the outer ring, oil groove and three lubrication holes. The inner ring has three edges. A fixed ring is installed in the center of the outer ring between the two rows of rollers to prevent the rollers from falling out and keep the bearing as a whole. This series of bearings can allow a certain axial displacement between the shaft and the bearing seat to occur in the bearing. Because it can be used as floating end bearing.
