Full complement cylindrical roller bearings are designed to withstand heavy loads. Under the same width, this kind of bearing has extremely high bearing capacity compared with the traditional bearing with cage, and the radial section is small, which can save space, but the speed is relatively low. All multi-row cylindrical roller bearings have a lubrication groove and lubrication holes in the outer ring. Full complement roller bearings are divided into single row, double row and multi row full complement cylindrical roller bearings according to the number of roller rows and whether they are self-aligning, or bidirectional positioning spherical roller bearings and bidirectional positioning non-aligning full complement roller bearings. The reason for this is that we want to better serve customers and provide customers with bearings that are more suitable for the working conditions of the main engine to ensure high efficiency and long life of the main engine. The dimensional tolerances and geometrical deviations of full complement cylindrical roller bearings shall comply with the GB/T307.1-94P0 tolerance level, and the normal original radial clearance CO, and bearings with C2 to C4 original radial clearance can also be required. However, the corresponding suffix should be added after the bearing code when ordering. Rubber and plastic screw extruders generally use C3 group clearance. If you need higher precision bearings, please contact our company directly. For the fit tolerance, please refer to the selection principle of bearing housing tolerance and the selection principle of shaft tolerance limit. Bearings are allowed to bear a certain axial load. Adequate lubrication is a prerequisite for bearing axial loads. The rib of one-way locating bearings and locating bearings that bear the axial load must be fully supported. Installation and disassembly, when installing or disassembling cylindrical roller bearings, special attention must be paid to the fact that the installation or disassembly force cannot be directly transmitted through the cylindrical roller and the ring rib. Full complement cylindrical roller bearings are designed to withstand heavy loads. Under the same width, compared with the bearing with cage, this kind of bearing can accommodate more rollers and has extremely high bearing capacity; but its allowable speed is much lower than that of the cylindrical roller bearing with a cage. Full complement double row cylindrical roller bearings have 4 structural types, 3 open structures and 1 sealed structure. All products are of non-separable design, with lubricating grooves and lubricating holes on the outer ring for easy lubrication. The inner ring of the bearing has 3 ribs, and the outer ring has no ribs. There is a fixed ring in the center of the outer ring between the two sets of rollers, which can prevent the rollers from running out and keep the bearing as one. The bearing can allow a certain axial displacement due to thermal expansion or between the shaft and the bearing housing. This displacement occurs inside the bearing, not the inner ring and the shaft or the outer ring and the housing. Therefore, the friction does not increase during the rotation of the bearing. Bearings of this type are suitable for use as floating end bearings. The outer ring of the bearing has no ribs, so the product of this structure can only bear radial load, not axial load. The inner ring of the bearing has 3 ribs and the outer ring has one rib. Axial positioning in one direction is possible. The outer ring is fitted with a snap ring at the other end, keeping the bearing in one piece. The snap ring is to prevent the bearing from being scattered during the handling process and cannot bear the axial load. This type of bearing can withstand high radial loads and unidirectional axial loads, thus enabling axial positioning of the shaft in one direction. In the other direction, it is used as a floating bearing. The outer ring of the bearing is split and fixed by some components, so it cannot bear axial load in one direction. The 2 split outer rings each have a rib for axial positioning in both directions.
