The first is cold disassembly. When disassembling smaller U-Joint With 2 Welded Plate Type And 2 High Wing Bearings, you can use a suitable punch to gently tap the side of the bearing ring to remove it from the shaft. A better method is to use a mechanical puller. The grip should act on the inner ring or adjacent parts. If the shaft shoulder and the bearing seat hole shoulder are provided with grooves that can accommodate the puller pull, the disassembly process can be simplified. In addition, some threaded holes are machined at the positions of the hole shoulders so that the bolts can push the bearing out. The forces required for large and medium-sized bearings are usually greater than those provided by machine tools. Therefore, it is recommended to use hydraulic power tools or oil injection method, or both. This means that oil holes and oil grooves need to be designed on the shaft.

The second type is hot disassembly. When disassembling the inner ring of needle roller bearings or various types of cylindrical roller bearings, the hot disassembly method is suitable. Two commonly used heating tools are heating ring and adjustable induction heater. The heating ring is usually used to install and remove the inner ring of small and medium-sized bearings of the same size. The heating ring is made of light alloy. The heating ring has radial slots and is equipped with an electrically insulated handle. If the inner rings of different diameters are often disassembled, it is recommended to use a tunable induction heater. These heaters can quickly heat the inner ring without heating the shaft. When removing the inner ring of a large cylindrical roller U-Joint With 4 Welded Plate Type Round Bearings, some special fixed induction heaters can be used.
