Rolling contact bearing for supporting heated rolls |
摘要 |
A rolling-contact bearing for a shaft journal wherein the outside diameter of the shaft journal is thermally insulated relative to the shaft through which a heat transfer medium flows. The bore of the inner race on the shaft journal is provided with a ceramic layer predominantly of zirconium oxide and a smaller among of yttrium oxide to reduce the heat transfer from the shaft journal to the rolling-contact bearing. The inner race also has lateral surfaces toward the elements securing the bearing on the shaft journal. Those lateral surfaces may be provided with a ceramic layer as well.
