Features of cylindrical roller bearing :

According to whether the ring has ribs and the number of rows, cylindrical roller bearings can be divided into many types, such as single-row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double-row cylindrical roller bearings such as NNU and NN. These different types of bearings differ in axial displacement and ability to withstand axial loads, and can meet the needs of different mechanical equipment.
Roller and raceway contact mode:
The rollers and raceways of cylindrical roller bearings are in line contact or trimmed line contact. This contact mode gives the bearings a large radial load capacity and is suitable for bearing heavy loads and impact loads.
Strong load capacity:
Due to its special line contact design, cylindrical roller bearings can withstand large radial loads and a certain degree of axial loads (depending on the specific model and design).
Low friction coefficient:
The friction between the rolling element and the rib of the ring of the cylindrical roller bearing is small, which makes the bearing very suitable for high-speed rotation, and its limit speed is close to that of deep groove ball bearings.
Compact structure and easy to separate:
The inner and outer rings of cylindrical roller bearings are usually designed to be separable, which is convenient for installation and disassembly, and can also adapt to the changes in the relative position of the shaft and the housing caused by thermal expansion or installation errors.
High precision requirements:
Cylindrical roller bearings have high requirements for the processing of shafts or seat holes. After the bearing is installed, the relative deflection of the outer ring axis must be strictly controlled to avoid contact stress concentration.
