High-temperature aligning ball bearings can be replaced with bearings of the same model and any national standard bearings. They feature a double-row spherical rolling element structure, capable of adjusting misalignment errors between the shaft and bearing housing, with an adjustable angle of 3-5°. In high-temperature environments, the shaft deformation can be self-adjusted slightly. For dusty environments, a sealed dustproof structure can be chosen. The temperature resistance range of the working conditions is 150° to 1200°, meeting requirements based on different materials.
