Difference of roller bearing NU212 and 6212
Cylindrical roller bearing NU212 and ball bearing 6212 have the same structure. But the rolling elements are completely different. One is a steel ball and the other is a cylindrical rolling element. Different rolling elements have different effects.
1. The carrying capacity is different: the contact surface of the roller is a straight line, however, the contact surface of the ball is a point. Under the same size, the bearing capacity of the cylindrical roller bearing is greater.
2. The noise is different: at the same speed, the larger the contact surface, the greater the noise during operation.
3. Different speeds: the contact surfaces of the rolling elements are different, and the speeds are different. If the contact surface is large, the speed is relatively slow, so the ball bearing has an advantage in the speed.
All in all, the different rolling elements of the bearings under the same structure cause their characteristics to be quite different. The most important thing is to choose the best one.

How to install conveyor bearings NU212:
1. To choose the correct way and special tools to replace and install the cylindrical roller thrust bearing. Note that the inner diameter of the inner ring of the bearing is consistent with the outer diameter of the shaft to avoid excessive expansion.
2. Straight roller bearing doesn’t run for a long time, the contact surface is relatively large, and it is easy to rust. We need to prevent rusting of mechanical parts through manual intervention. The most common method is to apply lubricating oil.
