One pair of link plates (34) are mounted to the bushing (14), and another pair of link plates (34) are mounted to the pin (16). Seals are positioned between the adjoining surfaces of the roller (12) and the bushing (14) and the adjoining surfaces of the bushing (14) and the pin (16) to prevent contamination of the adjoining surfaces. Additionally, the roller assembly (10) can utilize a reservoir (28) containing a pressurized, fluid lubricant and a pressure accumulator (30) to continuously supply lubricant to the adjoining surfaces of the roller assembly (10).
