The tapered roller bearing installation method is cold method, using the hammer and rod installation tools, such as to knock bearing, steel rod will lower in a rack or directly use the hammer knock be caused, mainly reflected in the improper operation load bearing cage with abnormal continuous impact force, cause the cage deformation at the same time guide roller and inner circle of small guard the impact, When the small retaining edge exceeds the impact load it can bear, brittle fracture occurs, resulting in bearing failure。
The correct installation method of tapered roller bearings

Enter the small end of the bearing into the journal first, and install the bearing to the specified position to fix it by knocking the big end.
