In the cylindrical air bearing installation

Of bearing inner ring with tight fit of the shaft and outer ring of bearing hole is a loose fit the separation type bearing for installation, can press the bearing installed on the shaft first, then the shaft together with the bearing to the bearing hole, if the bearing is lesser, also can use a soft metal hammer tap ring end face to force bearing, but striking force must be evenly distributed on the bearing ring. Bearing outer ring and bearing hole for tight fit, inner ring and shaft for a loose fit, the bearing can be installed on the shaft. When the bearing ring and shaft or bearing seat hole is a tight fit, the installation of the application of a special set of barrel at the same time the bearing pressure to the shaft or the bearing seat. Separation because the inner ring and outer ring of bearing installed easily loaded on the shaft or housing, respectively. At this point that should be noticed are will be insert has installed the axis of the inner ring has been packed outer ring of bearing box, try to keep it together, to prevent scratches rolling element and raceway. When bearing size is bigger, because the required installation force is bigger, or work under heavy load bearing fit interference is bigger and the cold installation are in trouble, you need to heat the bearing inner ring or bearing seat in advance before you install. When installed in hot, should strictly control the heating temperature. Maximum bearing heating, the heating temperature should not exceed 1200 c, should be in commonly 80 ~ 1000 c. With dust cover or seal bearing can't heating, otherwise it will cause loss of lubricant. Heating mode can be adopted electric induction wind, oil bath heating method, etc.
