A lubricated roller assembly which can be constructed entirely of non-metallic components. The roller assembly includes a shaft and roller body secured to one another and enclosed by a housing. The roller body is adapted to roll against an inner peripheral surface of the housing. A supply of lubricant sufficient to lubricate the roller body is contained within the housing. A lubricant containment reservoir is formed in either the housing or the shaft such that regardless of the orientation of the roller assembly, lubricant will not reach the interface between the shaft and the housing. The roller body may be provided with a drip edge to further direct lubricant away from the interface between the housing and the shaft. |
