Oil-free bearings when installation should pay attention to these things

1 oilless bearing installation must pay attention to these things. Should determine whether the mating surface of axis, the axis and shell have bruises, bumps, etc. 2. If there is a dust or sand mold is attached on the surface bearing shell. 3. Is slight bumps, bumps, etc. , if you have to fine sandpaper to remove stone or oil. 4. In order to avoid a collision during RongZhuang on, wipe the surface of the shaft and the shaft shell should be a small amount of lubricating oil. To install the bearing axis when applying pressure on the inner ring, bearing installed on the bearing shell, to applying pressure to outer ring. Applying pressure to the bearing, be sure to be careful to evenly, vertical force and partial play will make bearing were injured. Absolutely avoid to slant for this play. 5. Without oil bearing high temperature bearing retainer and sealing plate is absolutely not work. Use the hammer and the casing installation method, it is generally commonly used method, because can damage the bearing, so don't knock directly. Must be as shown in figure, make the socket interface in the middle and tapping into it. The hammer should be light light knocks. On the mechanical structure, inner and outer ring are tight fit, you should use plate, make sure power can also add to pressure in the rings. If only in the inner ring into tension, the force will dielectric ball and pressed into the outer ring, therefore, can cause scars in the orbital plane. To margin big bearing installed on the shaft, in clean oil, bearing heating to 80 ~ 90 degrees, the inside diameter expansion to install method, is widely used.
