Abstract
Disclosed is a pneumatic grease applicator includes a receptacle in which a retainer that forms a tubular axle selectively fit into a bearing to which grease is to be applied and a presser that defines a bore fit over the axle are movably received. The presser forms a top cavity in which a nozzle for coupling an external grease source is fixed. Grease is pneumatically supplied through the nozzle into the tubular axle and discharge through radially-extending holes defined in the axle to cover the bearing fit on the axle. An air vent is formed in the presser for pressure balance. Sealing members are provided between side wall of the receptacle and both the retainer and the presser to prevent leakage of grease.
