What is the Optoband?

The Optoband system ensures 100% control of the bearing rings, flanges and lamellae before assembly. The aim is to detect defects of surface, dimensions and flatness. The inspection takes place while scanning the parts stored on the conveyor. The parts are scanned sequentially from both sides. Scanning speed is up to 1000 mm / s. After inspection, the parts are automatically sorted into several groups, usually into two – surface defects and dimensional defects.
Depending on the requirements, it is possible to integrate the control of vertical pressed parts into the system, where various cracks and other mechanical damage occur.
