2. Whether there is dust or mold sand attached to the bearing housing surface.
3. Although it is a slight bump, bump, etc., if there is to remove the oil grindstone or fine sandpaper.
4. A small amount of lubricating oil shall be applied on the surface of shaft and shaft housing to avoid collision during loading.To install the bearing in the shaft, force must be applied in the inner ring. To install the bearing in the bearing housing, force must be applied in the outer ring.To apply force in the bearing, be sure to pay attention to make the force vertical and uniform down, deflection will make the bearing injury.To this end, absolutely try to avoid playing wide.
5. The retainer and sealing plate of oil-free bearing must not be applied.The installation method of hammer and sleeve is commonly used, because it will damage the bearing, so do not directly knock.Make sure the sleeve is inserted in the middle and knocked in, as shown.The hammer should be gently struck.In the mechanical structure, the inner and outer rings are tight with the use of plate, be sure to make the force can be added to the inner and outer ring pressure into.If only in the inner ring pressure, the force will be through the ball and pressure into the outer ring, therefore, will cause scars on the track surface.When the bearings with large tolerance are mounted on the shaft, they are heated to 80 ~ 90 degrees in clean oil to make the inner diameter expand for installation, which is widely used.
6. The hardness of the bearing may be reduced by overheating, so it must not exceed 100 degrees.At this point, the bearing must be suspended with steel wire, or placed on the wire mesh, support plate, do not place at the bottom of the groove.When the bearing reaches the desired temperature (below 100 degrees), it should be taken out of the groove immediately and quickly put into the shaft. The bearing will shrink as the temperature drops. Sometimes there will be a gap between the shaft shoulder and the bearing end face.
