An apparatus for measuring non contact type bearing start friction torque, is composed mainly of a loading cylinder (1), a force transducer (2), a loading housing (3), an air main shaft (5), an air bearing (6), a torque generator (7), a disk drive (8), an optoelectric transducer (9), an electrical system. The torque generator generates induction electromagnetic torque as drive torque, the optoelectric transducer monitors bearing start running state automatically; when being measured, the measured bearing is installed on the air main shaft, the disk drive is linked with the air main shaft and placed in the torque generator, the electrical system applies input power to the torque generator step by step after throwing axial load, when the induction electromagnetism drives the air main shaft to rotate through the disk drive, the optoelectric transducer matching-installed by the disk drive monitors the measured bearing from static state to start running state, and outputs signal to stop applying input power, and records current power value which is the start friction torque value of the measured bearing.
