Characteristics of tapered roller bearings and cylindrical roller bearings

Tapered roller bearings are centripetal thrust structures and can withstand both axial and radial forces. Among them, the single column 

can only withstand the axial force in a single direction, and some types can withstand the opposite axial force at the same time, 

similar to angular contact ball bearings, the difference is that the relative speed is low, the accuracy is low, but the bearing capacity 

is much larger.

Cylindrical roller bearings and deep groove ball bearings are very similar, but the bearing capacity is larger, the roller and the shaft 

are in line contact, the ball is in point contact, the general model is mostly to withstand radial force, axial force is not stressed or 

the force is very small (such as NJ series), the cylinder is good on the machine with large radial force, if the force is not so large it 

is recommended to use the same size ball bearings, but the spindle series is not one of them.
