Abstract
A method of lubricating a bearing (58) in a printing unit (14) includes the step of directing a quantity of grease into the bearing (58), and the step of directing pressurized air into contact with the grease. The bearing (58) supports a printing cylinder (16) for rotation in the printing unit (14), and includes a plurality of rolling elements (100) between a pair of opposed bearing race surfaces (94, 88). A predetermined quantity (160) of grease is directed to flow from a hydraulic pump (114) to the space between the bearing race surfaces (94, 88). The pressurized air is directed to flow from a pneumatic pump (132) into contact with the grease to remove a first portion of the predetermined quantity (160) of grease from the space between the bearing race surfaces (94, 88). The pressurized air further spreads a second portion of the predetermined quantity (160) of grease into coatings (190) which extend over the rolling element surfaces (104) and the bearing race surfaces (94, 88).
