Rollers for conveyor belts for quarries and concrete plants. For greater resistance to external conditions, all rollers are manufactured with stamped and calibrated sheet metal heads, welded to the hot-rolled steel shell with a thickness of ≥ 3mm. Precision ball bearings with permanent lubrication are always mounted, protected on the outside by double or triple labyrinth seals and on the inside by a lip seal that prevents grease leakage.
At the end of the production process, each roller is tested on a machine that keeps it rotating for the time necessary for the uniform distribution of the lubricant.
We can provide different types of rollers, according to our customers’ needs:
- idler rollers, for light or extra heavy loadings
- rubber coated impact rollers, spacers, cleaning helical rollers made of rubber or steel
- guide rollers and 2-rollers projecting units
- drum motor rollers
- drive drums and transmission drums
Steel idle rollers with watertight double labyrinth sealing assembled on first rate precision 6202 ball bearings with continuous lubrication. Tube with constant thickness and heads connected through soldering. The rollers are used on medium load belt conveyors moving at high speeds even in poor environmental conditions.
