Abstract
A greasing system for conveyor belt rollers uses a depression formed in a shaft about which the roller rotates to permit grease to flow from a front side to a backside of a roller bearing. In this way grease can be applied to the bearing while the conveyor is operating. The grease then flows from the backside of the bearing, through the bearing and out an outlet on the front side of the bearing making it easy to determine when the bearing has been fully greased.
