Correct Disassembly Method of FAG Bearings

Regardless of any type of bearing disassembly, professional disassembly methods are required, which are not understood by the mechanical engineers of various manufacturers. In order not to damage FAG bearings and mechanical parts, FAG bearings are also designed to be easy to disassemble. Therefore, according to the design concept It is also necessary to use different removal tools. Casual disassembly will affect the life of the machinery in the future, so experience is very valuable to us. Disassembly and installation must not be sloppy, and must be carried out carefully at the same time. There are several methods: 1. Disassembly of the FAG bearing outer ring Disassembly of the outer ring When disassembling, the base screws around the mechanical shell, that is, around the bearing, should be squeezed evenly with the screw rod. When disassembling, cover the screw hole with a blind plug to separate the bearing from the machine. The professional removal tool of the bearing is gently tapped to remove it. 2. The disassembly of FAG bearings with cylindrical bore and the disassembly of the inner ring. The disassembly of the inner ring is actually very simple. Use the bearing to pull it out, and pay attention to the pull-out force of the inner ring. 3. Disassembly of the inner ring of a large FAG bearing The oil pressure method is used to disassemble the inner ring of a large-scale bearing. Apply oil pressure through the oil hole to facilitate drawing. 4. The disassembly of FAG bearings with large width can be disassembled by using oil pressure method and drawing together. 5. The inner ring of NU type and NJ type FAG cylindrical roller bearings can be disassembled by using an induction heater to heat the part in a short time, and it is easy to pull out after the inner ring expands. 6. Removal of FAG bearings with tapered holes Generally, FAG bearings with tapered holes have an adapter sleeve, and the inner ring is supported by a block fastened on the shaft. After turning the nut, use a spacer to hit it with a hammer.
