An electromagnetic clutch for an air conditioner having improved rotational performance is provided to reduce noise of the clutch even if transferring high load as well as to rotate at high speed by placing 15 double radial bearings, which are bigger and more than before, to rotational center on the disk. An electromagnetic clutch(100) for an air conditioner having improved rotational performance comprises a lead wire(123), a coil(122), a pulley(121), a disk(125), and bearings(110). The lead wire, connecting a power generating unit to a compressor of an air conditioner, transfers an external control signal. The coil generates electromagnetic force by the lead wire. The disk is friction-combined with the pulley according to the electromagnetic force generated by the coil. The bearings, engaged with the power generating unit and the compressor, rotates the disk. The 15 bearings are placed with respect to a surface direction of the disk in two rows axially. The diameter of the bearing is 40mm.
