In principle, all joint bearing should be kept in their original packing before installation. They need to stay in a clean, free of moisture, relatively constant temperature environment. Joint bearing should stay away from dust, water and corrosive chemicals. Shaking and vibration will always be possible damage and mechanical properties of joint bearing, therefore, must avoid the vibration in the process of handling and storage.
Basically, all the joint bearing must be the level of preservation, because the joint bearing long time vertical some heavier after placement, can be deformed by its own weight. Pre-coated with grease (or seal) joint bearings need to be especially careful, because the grease after the density change after long time storage. So when the joint bearing is used for the first time, there will be a certain degree of rotation noise. Therefore, the bearings should be set aside time to control the FIFO principle.
On the shaft and bearing seat, a joint bearing requirements fixed in the radial, axial and tangential direction three position. Radial and tangential orientation through the tight fit of the joint bearing mining, axial position only in a few cases the use of tight fit; general axial spacing parts, such as the end cap and retaining ring to limit the axial position in the context of clearance.
