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.

Sl18 (NCF... V) type full loaded cylindrical roller bearing has a single retaining edge on the outer ring and a lock ring on the side without retaining edge, which can make one-way positioning for the shaft. The axial clearance "s" inside the bearing ensures the axial positioning movement of the shaft relative to the bearing housing.

Sl19 (NJ... V) type full loaded cylindrical roller bearing is used in extremely heavy load and low-speed occasions. It has a self-locking roller set. Even if the inner ring is removed, the rollers will not be scattered. Therefore, this type of bearing is easy to install and disassemble, and can bear one-way axial load for one-way positioning.
