Full loaded cylindrical roller bearing (full roller bearing) is designed to bear heavy load. In the same width, compared with the traditional bearing with cage, this bearing has very high bearing capacity, small radial section, can save space, but the speed is relatively low. All multi row cylindrical roller bearings have a lubricating groove and a lubricating hole on the outer ring. Full loaded roller bearings are divided into single row, double row and multi row full loaded cylindrical roller bearings according to the number of roller rows and whether they are self-aligning, or two-way positioning self-aligning roller bearings and two-way positioning non-self-aligning full loaded roller bearings. The reason is that we want to better serve customers and provide customers with bearings more suitable for the working conditions of the host, so as to ensure high efficiency and long service life of the host.
The dimensional tolerance and geometric deviation of full loaded cylindrical roller bearing shall meet the tolerance grade of grade P0 in GB / t307.1-94 (iso492-1994), and the bearing with normal original radial clearance CO can also be required to have C2 to C4 original radial clearance. But when ordering, we need to add the corresponding suffix after the bearing code. C3 group clearance is generally used in rubber plastic screw extruder.

The fit tolerance can refer to the selection principle of bearing seat tolerance and the selection principle of shaft tolerance limit.
The bearing is allowed to bear certain axial load. Adequate lubrication is a prerequisite for bearing axial loads. One way locating bearing and locating bearing, whose rib bearing axial load must be fully supported.
When installing or disassembling cylindrical roller bearing, special attention must be paid. The installation or disassembly force cannot be directly transmitted through cylindrical roller and ring flange.
