Do you know the types of full complement cylindrical roller bearings?

NNC/SL01 series full complement cylindrical roller bearings
NNC/SL01 series full complement cylindrical roller bearings are unsealed bearings. The outer ring is integrally split and is fixed by the connecting locking piece. Therefore, the outer ring can not bear the axial load. The outer ring after the splitting is It is exactly the same, each with a rib, which can be positioned in both directions. The inner ring has three ribs. The outer ring has oil grooves and three lubrication holes. These bearings are usually oil lubricated.

NNCL/SL02 series full complement cylindrical roller bearings
The NNCL/SL02 series of full complement cylindrical roller bearings are unsealed bearings with no ribs on the outer ring, oil grooves and three lubrication holes. The inner ring has three ribs. The center of the outer ring is equipped with a fixing ring between the two rows of rollers to prevent the roller from falling out and keep the bearing in one. This series of bearings allows a certain axial displacement between the shaft and the housing to occur within the bearing. Because it can be used as a floating end bearing.

NCF...V/SL18 full complement cylindrical roller bearings
NCF...V/SL18 full complement cylindrical roller bearings, the outer ring has a single rib, and there is a lock ring on the side without a rib. It can be unidirectionally positioned on the shaft, and the axial clearance "S" inside the bearing is guaranteed. The axial movement of the crankshaft relative to the bearing housing.

NJ...V/SL19 full complement cylindrical roller bearings
NJ...V/SL19 full complement cylindrical roller bearings for heavy duty and low speed applications, with self-locking roller set, even if the inner ring is removed, the roller will not be scattered, so the bearing is easy to install and disassemble. Can withstand one-way axial load for one-way positioning. Dimensional tolerances and geometrical deviations of full complement cylindrical roller bearings shall comply with the Class P0 tolerance class of GB/T307.1-94 (ISO492-1994), and normal original radial clearance CO may also require C2 to C4 original radial direction. Bearings for clearance. However, the order suffix should be added after the bearing code is ordered. Rubber and plastic screw extruders generally use C3 group clearance.

For tolerances, please refer to the selection principle of bearing housing tolerance and the principle of shaft tolerance limit selection. The bearings are allowed to withstand a certain axial load. Sufficient lubrication is a prerequisite for bearing axial loads. The unidirectional locating bearing and the locating bearing must be fully supported by the rib that receives the axial load. Installation and disassembly, special care must be taken when installing or disassembling cylindrical roller bearings. Installation or disassembly forces cannot be transmitted directly through the cylindrical rollers and the ferrule ribs.
