Abstract
A lubricating device for mounting on a spindle, such as a roll spindle, in which a split gear ring is mounted on the spindle and confined within a cover which has a pinion therein meshing with the gear ring and forming a lubricant pump therewith. The gear ring has axial hub portions thereon and there are bearings interposed between the cover and the hub portions rollingly supporting the cover on the hub portions. The cover is sealed to the hub portions and is held against rotation on the spindle.
