Built for harsh conditions - tight sealing, smooth running, long service life.

In mining, quarrying, cement, and bulk-material handling, conveyors run under constant stress - dust, moisture, slurry, and continuous duty cycles. Downtime is expensive, and roller failures often start with one thing: contamination reaching the bearings.

That’s why we created our new standard procurement product: ST-Idler PRO – Heavy-Duty Steel Conveyor Roller.

The ST-Idler PRO is engineered for demanding environments and long-term continuous operation. Its key strength is the optimized sealing package (labyrinth system plus protective elements), designed to keep dust, water, and slurry away from bearings and internal components - helping reduce premature wear and unplanned stops.

Combined with quality components, continuous welding, and controlled coating options, the ST-Idler PRO delivers consistent performance where it matters most: smooth running, reliable operation, and extended service life in real-world harsh conditions.
