New generation steel roller introduced Leading South Africa-based manufacturer and distributor of conveyor rollers, Megaroller has introduced a new generation steel roller to its hard-working rollers’ range for the mining and materials handling industries. M egaroller’s new, patent-pending steel rollers are designed to ensure accurate bearing alignment to a steel roller for use in mines underground. “Our new Megaroller is a revolutionary design concept for steel rollers. These rollers answer to the demand for a cost effective, more energy efficient and long- lasting steel roller that creates less noise pollution,” says Adrian Evans, business development manager at Megaroller.

quiet operation,” adds Evans. The rollers are produced in the com- pany’s ISO:9001-certified plant in Brits in the North West Province. This offers customers the assurance that the steel roll- ers adhere to the same high standards and quality principles for which the company has become renowned.  As with the Megaroller HDPE and hy- brid rollers, the bearings in the Megarollar steel roller are lubricated at the factory and placed in a protective housing that is completely sealed. This eliminates the need to lubricate at user level, prevents the risk of over or under-lubrication, and mitigates the risk of bearing failure due to lack of lubrication. Customers are also offered the option to have their rollers manufactured using the bearing brand of their choice. “The optimised efficiency and longer lifespan of the Megaroller steel roller, when compared to traditional steel rollers, mean that companies benefit from lower main- tenance costs and improved total costs of ownership.” says Sarel Koekemoer, general manager at Megaroller “At a time when cost curtailment is a business priority, these benefits will be increasingly valued by mining and materi- als handling companies,” he concludes. q

deliver easier rolling, enhanced efficiency and less noise pollution. Rolling easily, with less friction, the new steel roller is a long- lasting, environmentally friendly alternative to conventional steel rollers. New generation steel Megaroller rollers have bearing housings that are mechani- cally fixed instead of welded. This ensures superior bearing alignment to deliver a more efficient, quieter and longer lasting roller. Megaroller’s steel conveyor roller fea- tures cushioned bearing carriers made from high quality nylon to provide vibration and shock protection at the most crucial part of the roller. This additional barrier, unique to Megaroller rollers, enhances impact resistance and guards the bearing against vibration, one of the main causes of roller failure. This is the first time that these benefits have been made available in

Megaroller, which was the first manu- facturer to produce high-density polyeth- ylene (HDPE) conveyor rollers in the early 1980s, has applied for a patent on the me- chanically fixed steel housing arrangement. “This is what differentiates our steel roller from conventional steel rollers avail- able on the market. It is the welding-on of the bearing housings that causes them to warp, resulting in bearing misalignment and premature bearing failure. “Our steel rollers have been tested at several customers’ sites and feedback has been excellent. The rollers have proved to outlast other conventional steel rollers and our customers are impressed with their
