To provide a bearing for a compressor less loaded by hydraulic pressure and having a large cooling effect on the rotor shafts.
In this bearing 7 for the compressor supporting the rotor shafts 5, 6 of a compressor 1, a first oil groove 13 is formed in the bearing surface 12 on the opposite side of the side on which a bearing load P1 acts and a second oil groove 14 is formed in the bearing surface adjacently to the first oil groove 13 counterclockwise. Oil supply holes 16, 17 for supplying an oil to the first oil groove 13 and the second oil groove 14 from the outside are formed in the bearing surface. The length S of the second oil groove 14 in the circumferential direction is longer than the length of the first oil groove 13 in the circumferential direction. The size of the oil supply hole 17 at the second oil groove 14 is smaller than the size of the oil supply hole 16 at the first oil groove 13.
