The invention discloses a TC bearing and a manufacturing method thereof. Paste nickel base brazing material is adopted to conduct a preparation, the brazing material is smeared directly between a steel bonded hard alloy and a steel body, and then a vacuum brazing method is adopted to conduct the preparation. According to the TC bearing and the manufacturing method thereof, the steel bonded hard alloy is adopted, so that welding stress in the process of brazing is reduced; brazing bond strength is increased; the problem that a hard alloy falls off in the process of using is avoided; and meanwhile the remelting problem caused by the fact that brazing is not in place is avoided, and surface hardness is guaranteed.
