This invention relates to the field of aero-engine bearing testing technology, and discloses a bearing testing device, including a main shaft, a test bearing assembly, a sealing structure, and a maintenance assembly. The test bearing assembly includes a first bearing housing and a test bearing. The first bearing housing has a first air inlet. The adjusting ring of the maintenance assembly has a first end and a second end. An oil injection ring is spaced apart from the second end to form a sealing channel. A stationary ring is connected to the oil injection ring and positioned close to the second end. The first air bleed channel of the oil injection ring communicates with the second air bleed channel, and the first air bleed channel communicates with the first air inlet. The other end of the second air bleed channel communicates with the sealing channel. This invention, through the spaced arrangement of the rotating and stationary rings and the airflow guidance of the sealing channel, introduces high-temperature gas through the first air inlet of the first bearing housing and guides it into the sealing channel, recreating a real sealing scenario. This makes the bearing test verification more comprehensive and closely resembles the actual working condition, significantly improving the reference value of the test data.
