Common problems and FAG bearing installation considerations

FAG bearings and bushings, seat, bearing hole clearance fit transition commonly, two-way thrust bearing ring should be fixed on the shaft, in order to prevent the relative rotation axis bearing installation method, under normal circumstances, in most cases axis, so woo of inner ring and shaft bearings and bearing clearance fit outbuilding bearing installation, you should check the ring and shaft sleeve centerline axis vertical dial gauge fixed on the tank, will face a touch FAG bearing, axis bearing raceway header, at the same time observe the dial gauge pointer, if the pointer deflection, ring and the axis of the shaft sleeve is not vertical center box shell hole deep, also can use the extension of dial instrument bearing installation is correct, the seat can automatically adapt to the body, to ensure that the agency is located in the rolling up and down the wrong if, not only bearing is not normal work, and cooperate with the surface will be badly worn because of the difference of bearing seat ring and ring is not clear, the assembly should be careful, don't make a mistake in addition, the bearing race and a hole between 0. 2 - 0. 5 mm gap, to compensate for the machining of the parts, installation errors caused by inaccurate, operations center offset bearing rings, this space, in order to ensure the automatic adjustment, avoid contact friction of normal operation, otherwise FAG bearing will cause serious harm. 1. Assembly site should be kept clean, no dust. 2. To avoid a FAG bearing from dust, moisture and contaminants - Pollutants have a bad effect on the running and service life of bearing. 3. Check the bearing hole and the shaft with the following: geometry and dimensional accuracy, and cleanliness. 4. For bearing ring mating surface coated with a little oil or a little fat. 5. To ensure that the shaft and bearing hole has a 10 degrees - Guide the chamfering of 15 degrees. 6. Don't be cool bearing: condensation of water can lead to bearing and the bearing of mating surface rust. 7. After installation, loading the FAG bearing lubricant, check whether the bearing configuration is working properly.
