Description:


Cylindrical roller bearing raceways and rolling elements are geometric. The high structural capacity, the new structural design of the rib and the roller end face not only improve the axial bearing capacity of the bearing, but also improve the lubrication condition of the contact area between the roller end face and the rib, and improve the performance of the bearing.


tres

1. The roller and the raceway are in contact with the wire or repaired, and have a large radial load capacity, which is suitable for bearing heavy loads and impact loads.


2. The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing.


3. N-type and NU-type can move axially, can adapt to the change of the relative position of the shaft and the shell caused by thermal expansion or installation error, and can be used as free-end support.


4. The machining requirements of the shaft or the seat hole are high. After the bearing is installed, the relative deflection of the outer ring axis should be strictly controlled to avoid contact stress concentration.


5. The inner or outer ring can be separated for easy installation and removal.
