The unique Melco Turnback Collar Type Housing Design is a result of the combination of many years of experience in the conveyor industry and the knowledge of the art of deep drawing of steel. Utilising 7 and 8 stage forming processes on 200ton machines, Melco produces bearing housings of the highest quality ensuring correct bearing alignment and fits. The Melco roller features a welded Monobloc construction. The bearing housings are turned back to ensure accurate concentric assembly. Tube wall thickness is maintained at the tube/bearing housing mating surface. Multiple step deep drawn bearing housings ensure that wall thickness is also maintained at all critical points.
