These rollers are particularly rugged and smooth running, they are made of steel with permanently lubricated rigid radial ball bearings.
The tube is swaged guaranteeing a perfect assembly with the end-caps.
The shaft is internally threaded for screw fixing: with this type of installation the conveyor is stronger and more rigid.
The particular shape of the end-caps, the assembly accuracy and the type of bearings employed make these rollers functional for driven and belt conveyors in industrial applications.
Application temperatures range from –20° C to +100° C.
