For a consistent level of quality during the manufacturing of the shafts and tube assemblies, we install our idlers on a fully automated assembly line.
Seven robots assemble the individual components into a roller with an output of one roller per minute, checking and recording all important quality parameters in the process.
Every roller is checked for axial clearance, TIR (total indicated runout), and resistance to rolling. Our premium rollers are also checked for imbalance, which is simultaneously countered in an integrated welding station where the corresponding balancing weights and dust covers are applied..
These covers are aligned and pressed into the rollers. Subsequently, the balance results are checked again.
Return rollers are automatically equipped with rubber or polyurethane rings and finally secured with welded-on end rings.
