The invention discloses an oil-driven variable-distance multi-rotor aircraft bearing rack, relates to a bearing rack for an oil-driven variable-distance multi-rotor aircraft, and mainly aims to solve the problems that a conventional rack of the oil-driven variable-distance multi-rotor aircraft is low in strength, small in bearing capacity and the like. The oil-driven variable-distance multi-rotor aircraft bearing rack comprises a plurality of arms, wherein positioning triangular plates, upper bearing tubes and lower bearing tubes are arranged on the arms; the upper bearing tubes on adjacent arms are connected; the other ends of the lower bearing tubes are communicated with a hollow base; the upper bearing tubes and the lower bearing tubes of the arms are welded with the positioning triangular plates; the lower ends of middle bearing tubes are communicated with the hollow base; the upper ends of the middle bearing tubes are inserted into connectors of two adjacent upper bearing tubes; two ends of an upper holl
