Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a precision bearing transportation packaging box. Background Art

[0002] Precision bearings require extremely high machining and assembly accuracy. As important mechanical components, it is particularly important to use appropriate bearing packaging to prevent bearings from being damaged during transportation and storage. If the packaging design is unreasonable, the bearing surface will be damaged due to vibration and impact during transportation, resulting in loss of use value and causing great economic losses. The existing stacking packaging method for bearings is prone to displacement and friction between the bearing surfaces during transportation and handling, and the bearings will also move and collide in the packaging box, which can easily cause direct damage to the bearing surface, thereby affecting the surface accuracy of the finished bearing.
