<p>A bearing for refrigerating machine compressor and a compressor having the bearing, wherein the bearing (1) comprises a porous bronze (1b) and resin (1c) impregnated into pores provided on the porous bronze (1b) which are formed on a back metal (1a), the porous bronze (1b) and resin (1c) are exposed sparsely on the surfaces in contact with a crank shaft (5), the rate of the exposed area of the porous bronze (1b) on the contact surface (1d) is 5 % or over to 60 % or less, whereby a seizure resistance at the time of boundary lubrication of the bearing for refrigerating machine compressor can be increased and the amount of wear due to sliding of the bearing can be decreased.</p> |
