PURPOSE:To utilize the solid lubricant powder unwastefully and effectively by recovering the excess solid lubricant powder not used for the lubrication of a rolling bearing with the third carrier gas and utilizing both of them for the lubrication of the bearing again. CONSTITUTION:The powder not used for the lubrication in a rolling bearing J among the powder fed to the bearing is stuck to the outer face of the bearing J and the inner wall face of a bearing chamber R. The third carrier gas controlled by the third control valve V3 for its flow quantity is fed to a blowing-off device M and sprayed through a nozzle (n) to blow off the powder stuck to the outer face of the bearing and the inner wall face, the powder is dispersed in the third carrier gas to form the second mixed gas of them. This second mixed gas is separated into powder and gas in the tank 38 of a separator S. The accumulated powder is discharged to a separator B and utilized again.
