Full complement bearing.com/cylindrical-roller-bearings.html' target='_blank'>cylindrical roller bearing is a type of bearing, which means that because there is no cage, it can accommodate a very large number of rollers. It is generally used in machinery. Most people only know about bearings, but they don't know much about full complement cylindrical roller bearings. Next, the editor will explain to friends the type and basic layout of full complement cylindrical roller bearings. Full complement cylindrical roller bearings (full complement bearings) are designed to withstand heavy loads. At the same width, compared with the traditional bearing with cage, this kind of bearing has a very high load capacity, a small radial section, 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 Yunyun 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 performance and long life of the main engine. The size and error of full complement cylindrical roller bearings should conform to GB/T307.1-94 (ISO492-1994) P0 grade, and the usual original radial clearance CO can also be required to have C2 to C4 Bearings with original 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. The joint operator can refer to the selection criteria of the bearing seat and the limit selection criteria of the shaft operator. Bearings are allowed to suffer a certain axial load. Adequate lubrication is a prerequisite for axial loads. The rib of the one-way locating bearing and locating bearing that is subjected to the axial load must be fully supported. Placement and destruction, special attention must be paid when installing or destroying cylindrical roller bearings, the installation or destruction force cannot simply be transmitted through the cylindrical roller and the rib of the ring. What is a full complement cylindrical roller bearing? Full complement cylindrical roller bearings are designed to withstand heavy loads. At the same width, compared with the traditional bearing with cage, this kind of bearing has a very high load capacity, a small radial section, which can save space, but the speed is relatively low. In order to make the bearing work normally, in the case of continuous operation, the bearing must be subjected to a certain very small load, namely 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 lubrication groove and lubrication holes in the outer ring. Full complement cylindrical roller bearing example 1. It has two inner rings. The two inner rings are connected together by a clamping ring, which cannot be separated. Because the distance between the two rows of rollers is large, the overturning moment can also be suffered. There are two retaining grooves on the surface of the outer ring, which can be positioned axially. This type of bearing is equipped with contact sealing rings on both sides and lithium base grease inside, and the operating temperature is limited to -40℃～+80℃. Under certain conditions, this type of bearing does not need maintenance, but when there is water vapor or pollution during operation, and it is often operated at medium or high speed, it must be lubricated. In places where oil lubrication is used, the sealing ring needs to be removed, and the grease in the bearing should be cleaned. 2. It is a non-sealed bearing, the outer ring is integrally split, and is fixed in one way by the connecting lock piece, so the outer ring cannot bear the axial load, the split outer ring is completely the same, each with a rib, Two offset axial positioning is possible. The inner ring has three ribs. The outer ring has oil grooves and three lubrication holes. This series of bearings is usually oil lubricated. 3. It is a non-sealed bearing, the outer ring has no ribs, and has oil grooves and three lubrication holes. The inner ring has three ribs. A fixed ring is installed in the center of the outer ring between the two rows of rollers, which can 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 be generated in the bearing. Because it can be used as a floating end bearing 4, the outer ring has a single rib, and there is a lock ring on the side without a rib, which can be used for one-way positioning of the shaft. Axial positioning shift. 5. It is used for deep and heavy loads and low-speed places. It has 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 destroy, and can withstand one-way axial load for one-way positioning. . The basic example of full complement cylindrical roller bearings Full complement cylindrical roller bearings can withstand overturning moments in addition to very large radial and axial loads, so they are long used as fixed bearings. The outer ring of NNC 49V series bearings has a lubricating oil groove and several lubricating oil holes, which can also be lubricated in the shaft during operation. Both ends of NNF50B.2LS.V and NNF50C.2LS.V series bearings accept contact seals, and the seals are filled with grease. In the case of better application conditions, the grease can reach the working life of the bearing. Lubrication is possible through lube grooves and lube holes on the outer ring. If the same several bearings are placed on a shaft, the rotational speed of the outer ring can be different because the outer ring is narrower than the inner ring. This is somewhat suitable for the pulley mechanism. In order to easily fix the pulley to the outer ring of the bearing, there are annular grooves on both ends of the outer ring of the bearing that can be installed with elastic retaining rings.
