Product description

Full loaded cylindrical 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. In order to make the bearing work normally, under the condition of continuous operation, the bearing must bear a certain minimum load, that is, C / P < 25. Otherwise, due to insufficient lubrication and high-speed operation, it will aggravate the wear. All multi row cylindrical roller bearings have a lubricating groove and a lubricating hole in the outer ring. It has two inner rings. The two inner rings are connected by clamping rings and can not be separated. The outer ring has a middle rib, which can bear two-way axial load and is used as positioning bearing. Because of the large distance between the two rows of rollers, it can also bear the overturning moment. There are two stop grooves on the outer ring surface, which can be positioned axially. Both sides of the bearing are equipped with contact sealing rings, which are filled with lithium grease. 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 often runs at medium or high speed, it must be supplemented with lubrication. In the case of oil lubrication, it is necessary to remove the seal ring and clean the grease in the bearing. When oil lubrication is used, the rotating speed can be increased by 30%. Series full loaded cylindrical roller bearings

Series full loaded cylindrical roller bearings NNC / SL01 series full loaded cylindrical roller bearings are unsealed bearings. The outer rings are integrally split and fixed together by connecting locks. Therefore, the outer rings can not bear axial load. The split outer rings are exactly the same, each with a rib, which can be used for axial positioning in two directions. The inner ring has three ribs. The outer ring has an oil groove and three lubrication holes. This series of bearings are usually oil lubricated
