The Advantages of the Cylindrical Roller Bearings

Publish Time:2019.04.22


The cylindrical roller is in line contact with the raceway and has a large radial load capacity. Suitable for both heavy and shock loads, as well as for high speed rotation. Cylindrical roller bearing raceways and rolling elements are geometric. After the improved design, the new load-bearing 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 conditions of the contact area between the roller end face and the rib, and improve the lubrication condition. Bearing performance. So here is the analysis of its five advantages:


1. Roller and raceway are in line contact or repair line contact, and have large radial load capacity, suitable for heavy load and impact load.


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


3. The 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 a free end support.


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


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


Cylindrical roller bearings are also widely used, large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transporting machinery.
