Difference of roller bearing NJ210 and 6210
Ball bearing rollers NJ210 bearing and 6210 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.
