The lubricating oil of the bearing must be kept clean. Even very small dust will have a bad impact on the bearing. Therefore, keep the surrounding clean so that dust will not invade the bearing.
The deep groove ball bearing is strongly impacted in use, which will produce scars and indentation, which will become the cause of the accident. In serious cases, it will crack and fracture, so we must pay attention to it.
Avoid replacing with existing tools and bearing tools, and appropriate tools must be used. We often emphasize the importance of tools because too many customers use the wrong tools in installation, resulting in bearing damage.
On the shaft and in the bearing pedestal, the deep groove ball bearing is required to fix its position in three directions: radial, axial and tangent directions. Radial and tangential positioning is realized by tight fit of bearing ring, and tight fit is adopted for axial positioning only in a few cases; Generally, axial limit parts, such as end caps and retaining rings, are used to limit the axial position within the clearance range.
The following four points should be paid attention to when selecting the fit:
(1) The circumferential surface of bearing ring shall have good support and uniform stress to reduce deformation and give full play to the bearing capacity of deep groove ball bearing.
(2) The ferrule cannot slide along the tangent direction in its mating surface, otherwise the mating surface will be damaged.
(3) The free end bearing must be able to adapt to the length change of the shaft and bearing seat hole, that is, it must have the ability to adapt to the swimming of the axial position within a certain range.
(4) Attention must be paid to making the installation and disassembly of deep groove ball bearings simple, labor-saving, time-saving and cost-saving. When operating the bearing, the sweat on the hand will become the cause of rust. Pay attention to operate with clean hands and wear gloves as much as possible.
