Disclosed is a pneumatic grease applicator includes a receptacle in which a retainer that retains a bearing to which grease is to be applied and a presser that securely holds the presser on the retainer are movably received. The receptacle has a bottom nozzle through which grease is continuously supplied from an external source under a pneumatically induced driving force, whereby the grease can be consecutively applied to a number of bearings without interrupts. Sealing members are provided between the retainer and the presser and side wall of the receptacle to prevent leakage of grease.
