Martin® Roller Tracker™
Martin Engineering has introduced a more effective return belt tracking system that uses high-quality materials for easier maintenance and a longer unit life. Building upon the standard crowned roller, the Martin® Roller Tracker™ uses a unique ribbed lagging made of durable polyurethane to increase performance and wear life. The roller does not come in contact with the belt edge, which means no fraying and excellent tracking for single-direction or reversing belts. The result is more centered cargo loading, less spillage and increased safety from the hazards of belt wander, leading to higher productivity and a lower cost of operation. It's Used for lower tension belts from 500-1500 mm (20-60 in.) in width, running at a speed of up to 5 m/s (984 fpm), crowned roller trackers have a slightly larger diameter at the center than at the edges. Realignment is based on the basic principle of the belt contacting the raised portion of the raised portion of the roller first (the crown) first.
