Ultrasonic testing of discs and rings

The SIRO-MAN ultrasonic inspection system reliably inspects discs, rings and shafts. These are then further processed and used in large gearboxes as well as ball bearings, e.g. in wind turbines.

Application: Ultrasonic testing of bearing rings and gears for wind turbines

Due to the high requirements of bearings for wind turbines, the rings are inspected with a SIRO-MAN at various stages of production. In the event of a material defect, this makes it possible to derive the appropriate steps at a very early stage in the manufacturing process.

Other rings are further processed into gears after ultrasonic testing with the SIRO-MAN. The inspection before the further processing of the rings makes it possible, for example, to set the milling contours in later production steps in such a way that the defect is no longer located in the component.

Inspection task

  • Reliably inspects discs, rings and cylindrical components
  • Two turning devices with equal load capacity
  • Parallel inspection and loading enables increased throughput
  • Depending on the configuration, one or more turning devices/roller blocks to reduce set-up times


Flexible and reliable system for different-sized components

  • No time-consuming turning of the workpieces is necessary
  • The swivel axis enables ultrasonic testing of the top and bottom side
  • Inspection of components on the outer surface (circumference) as well as from the bottom and top face
