Detection of Faulty Wheel Bearings on Railcars in Foundries via Vision Sensors

In steel foundries, railcars are used to transport cast parts weighing tons. To prevent downtime and repair costs and to increase the safety of the rail-guided carriages, the wheel bearings must be checked for damage during operation. Two vision sensors mounted below the carriages create an image of each wheel bearing shell. If damage such as a missing lid or missing balls is detected, the sensor reports this. Thanks to the integrated illumination, it delivers reliable results, even in extremely dirty, dusty and dark environments.
