These chains will take advantage from improvements on the friction of the rollers, so we can offer 25% extra accumulation length with the same pressure on conveyed products as before the change. For example, if with the old version it was possible to make 6m long conveyors, with the new version this will be 7.5 meters! Old and new MCC LBP chains are fully interchangeable and can be connected without difficulties. All code numbers will stay the same. No modification is needed on sprockets; furthermore no changes are necessary to the conveyor.
