A conveyor-belt roller assembly secured inside a conveyor-belt roller and onto an inner shaft, preferably used in conveyor-belts used for carrying high loads of material in hazardous environments. The conveyor-belt roller assembly has a stationary anti-lock shield which protects the rotating exterior surface from coming into contact with the outside elements for example debris and machinery. A dust shield is also position aft of the anti-lock shield to prevent the penetration of small particles and dust into the inner workings of the conveyor-belt roller assembly. The conveyor-belt roller assembly also has deep rings in the load-bearing portion for thermal expansion and contraction as well as heat dissipation. Bridging ribs are positioned across the deep rings to greatly increase the strength and therefore load- baring capacity of the conveyor-belt roller assembly. A tapered labyrinth seal is used so that it can be press locked into position making installation quicker and easier. The main load-baring component and tapered labyrinth seal component are preferably fabricated from a high strength, heat resistant 30% glass filled polypropylene.
