How to correctly install the back to back taper roller bearing?

When installing the back to back taper roller bearing: 

1. Pay attention to the back to back taper roller bearing direction of the bearing. When installing the outer ring or inner ring of the back to back taper roller bearing, it is best to use copper, wood or other soft material to pad on the shaft ring to prevent the bearing from being broken or deformed by the impact of strong and hard. Especially when hammering. At the same time, it should be prevented from being placed on the ring of the bearing.
2. To remove the burrs on the seat or shaft to be installed, guide the chamfer and apply grease or grease.

3. Bearings that are tightly coupled with the shaft should be installed after oil heating or electric heating.

4. For back to back taper roller bearing with slower speeds or difficult to refuel in the future, apply sufficient grease to the bearings when installing the back to back taper roller bearing.
5. For the installation of the ball bearing, the force is applied to the inner ring when it is mounted on the shaft, and the force point should be on the outer ring when it is mounted on the seat. If the inner and outer rings are installed at the same time, it is better that the inner and outer rings can be stressed at the same time.
6, pay attention to the verticality of the bearing when installing the bearing, and adjust the position of the back to back taper roller bearing perpendicular to the shaft or seat at any time. Can not be biased to one side.

Back-to-back configuration, the rear code is DB (eg 70000/DB), and the load lines of the back-to-back matched bearings are separated from the back to back taper roller bearing shaft. It can withstand axial loads acting in both directions, but the load in each direction can only be absorbed by one bearing. Back-to-back mounted bearings provide a relatively rigid bearing configuration and can withstand overturning moments.

back to back taper roller bearing must be installed in pairs. Both methods are correct. They are only the fulcrum of the force, which has an effect on the stiffness of the support shaft. The closer the stiffness between the two points, the better the stiffness, face-to-face installation and back-to-back installation. It depends on the specific situation. When back to back taper roller bearing are installed in pairs, they are face-to-face and back-to-back depending on the load. Mainly due to the fact that tapered roller bearings generate additional axial forces while being loaded, they are typically used in pairs to eliminate additional axial forces. When installing back-to-back, if the force point is on the outside, the force is applied to the fulcrum, which reduces the strength requirement of the load on the shaft. If the load is in the middle, the strength requirement of the load on the shaft is increased.
