1. The applying of the resultant force can do through the axis of the bearing, it needs the screws even symmetry and smooth, spherical or parallel to the axis force application.
2. The size of the wire should be smooth and uniform, should not have impact, it needs to choose hydraulic smooth or with can exert tension or stress, real had to choose hammer, also should pass to soft without exfoliation metals such as copper sleeve to buffer, tapping force can gently.The best use of copper rod or copper hammer hammer.
3. Drag to continue to the proper level, for example in the gear bearing in the bearing fit to the accurate position to suspend the work, make sure the rings (washers) face rely on a hole or shaft shoulder end, neither packed too tight, nor does not reach the designated position.
4. Prevent after the rolling body force, this demand inner ring (circle) shaft installation when applying pressure through the inner ring and outer ring installation) through the outer power works.
