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 on 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 rotation speed will be increased by 30%.

NNC / SL01 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. Outer ring with oil groove and three lubrication holes, this series of bearings are usually oil lubricated.

Nncl / sl02 series full loaded cylindrical roller bearing

Nncl / sl02 series full loaded cylindrical roller bearings are unsealed, with no rib on the outer ring, oil groove and three lubrication holes. The inner ring has three ribs. The center of the outer ring is equipped with a fixed ring between the two rows of rollers, which can prevent the roller 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 occur in the bearing. Because it can be used as a floating end bearing.

NCF... V / sl18 full loaded cylindrical roller bearing

NCF... V / sl18 full loaded cylindrical roller bearing has a single rib on the outer ring and a lock ring on the non rib side, which can make one-way positioning for the shaft. The axial clearance "s" inside the bearing ensures the axial positioning of the shaft relative to the bearing box.

NJ… V / sl19 fully loaded cylindrical roller bearing

NJ… V / sl19 type full load cylindrical roller bearing is used for extremely heavy load and low speed occasions. It has self-locking roller group. Even if the inner ring is removed, the rollers will not be scattered. Therefore, this type of bearing is easy to install and disassemble, and can withstand unidirectional axial load for unidirectional positioning. 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.
