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, roughly bidirectional positioning spherical roller bearings and bidirectional positioning non-aligning full complement cylindrical roller bearings , The reason for this is that we want to serve customers better, and provide customers with bearings that are more suitable for the working environment of the host, so as to ensure the high performance and long life of the host. The size and geometric deviation of the full complement cylindrical roller bearing should conform to the GB/T307.1-94 (ISO492-1994) P0 level, and the normal original radial clearance CO can also be required to have C2 to C4 original Bearings with radial clearance. 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 bearings with higher precision, please contact our company. For cooperation, please refer to the selection principle of bearing seat and the limit selection principle of shaft. Bearings are allowed to suffer certain axial loads. Adequate lubrication is a prerequisite for bearing axial loads. One-way locating bearings and locating bearings must be fully supported by their ribs that are subjected to axial loads. 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 simply be transmitted through the cylindrical roller and the ring rib. Cylindrical rollers and raceways are linear contact bearings. The load capacity is large, and it is mainly subjected to radial load. The friction between the rotating body and the rib of the ferrule is small, and it is suitable for high-speed torsion. According to whether the ring has ribs or not, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. The bearing has a separable layout of the inner ring and the outer ring. Cylindrical roller bearings with no ribs on the inner or outer ring, the inner and outer rings can be relatively moved in the axial direction, so they can be used as free end bearings. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction. Commonly used steel stamping cages, or copper alloy turning solid cages. But there are also applications of polyamide forming cages. Bearing features 1. The roller and the raceway are in line contact or trimmed line contact, and the radial bearing capacity is large, suitable for heavy loads and impact loads. 2. The conflict coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing. 3. N type and NU type can be moved axially, which can adapt to the change of the relative position of the shaft and the shell caused by thermal expansion or installation error, and can be used for open end support applications. 4. The processing requirements for the shaft or seat hole are relatively high. After the bearing is installed, the deflection of the outer ring axis must be strictly controlled to avoid intensive contact stress. 5. The inner ring or outer ring can be separated for easy installation and removal.
