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).

A method of lubricating an apparatus including a first rotatable member (16), a second rotatable member (18), and bearing means for supporting the rotatable members (16, 18) to rotate, the bearing means including a bearing (58) having a plurality of rolling elements (100) in the space between a pair
A method of lubricating an apparatus including a first rotatable member (16), a second rotatable member (18), and bearing means for supporting the rotatable members (16, 18) to rotate, the bearing means including a bearing (58) having a plurality of rolling elements (100) in the space between a pair of opposed bearing race surfaces (88, 94) which rotate relative to each other upon rotation of the rotatable members (16, 18), the rolling elements (100) having surfaces (104) supported in rolling contact with the bearing race surfaces (88, 94), said method comprising the steps of: a) rotating the rotatable members (16, 18); b) initiating and subsequently terminating a flow of substantially air-free grease into the space between the bearing race surfaces (88, 94) while the rotatable members (16, 18) continue to rotate, said flow of grease being terminated when an initial quantity (160) of grease has thereby been placed in said space, said initial quantity (160) of grease comprising a full load of grease which extends throughout said space; and c) initiating and subsequently terminating a flow of grease-free pressurized air into said space while the rotatable members (16, 18) continue to rotate, said flow of pressurized air being initiated after said initial quantity (160) of grease is placed in said space and thus being directed against said full load of grease; said flow of pressurized air spreading a first portion of said initial quantity (160) of grease into coatings (190) which extend over the rolling element surfaces (104) and the bearing race surfaces (88, 94), said flow of pressurized air removing a second portion of said initial quantity (160) of grease from said space, said second portion of said initial quantity (160) comprising substantially all of said initial quantity (160) which is not included in said coatings (190).
