This design, which seeks to improve service life, has a 20 per cent higher load rating than the US Conveyor Equipment Manufacturers Association (CEMA) standard. The inner tube insulates the bearing from vibration, reducing misalignment and increasing the life of the bearing.
As the outer shelf wears, the inner tube maintains the structural integrity of the roller. The double tube models are available in belt widths up to 305cm (120”) and are equipped with bearing sizes up to 60mm.
Superior Industries will be appearing at bauma 2019 and is seeking to develop new relationships with construction equipment dealers and distributors in Europe, the Middle East and Africa.
