Superior Industries, Inc., a US-based manufacturer and global supplier of bulk material processing and handling systems, has announced what it says is the most significant redesign to conveyor idlers in decades.

This update is backed by a substantial $4.5 million investment in cutting-edge idler manufacturing equipment at its US production locations, the company says.

According to Superior Industries, these are the key innovations of the new idler design:

• Ironclad weld joint at tube to end disc: a flush end disc prevents material entrapment between the roll and frame, while a weld bead is securely housed within the roll’s structure, ensuring added durability. This also comes with modern, robotic welding for greater weld penetration and extreme consistency;
• Revamped designs of idler bearing seals: a decade of rigorous testing results in an unmatched bearing protection system, according to the company, with the lifespan of standard bearing seals surpassing all other models tested. The Premium Titanium® seal, in this case, provides extended longevity for demanding applications; and
• Major upgrade to idler manufacturing:Improving industry-leading pace, Superior says it has achieved new heights in manufacturing speed. The manufacturing production rate of standard and custom idlers has witnessed a 35% increase, while the integration of robotic manufacturing ensures a level of consistency previously unseen.

Jason Adams, President of Superior, said: “Tens of thousands of Superior idlers are installed on our own conveyors every year, so roll performance really, really matters. The new idler exceeds our own high performance standards and we’re excited for other conveyor owners and operators to benefit from this upgrade.”
