High-temperature mounted bearings are in accordance with national standards, and any national standard bearing of the same model can be replaced. The internal structure of the high-temperature design includes both shielded and unshielded types, distinguishing between high and low speeds (rpm divided by 100 as the boundary). The spherical bearings have slight self-aligning capability, low installation requirements, mainly bear radial loads, and feature a single row of rolling elements. The bearing design operates within a temperature range of 150-800°C.
