Ball Scanners Wet – for wet inspection of surface and sub-surface of steel balls

Ball Scanners are sorting machines for the non-destructive inspection of the quality of the surface and sub-surface of bearing balls. The inspection is conducted by means of electromagnetic eddy currents (ECT tester), optic laser beam (EOT tester) and vibration integrated accelerometer (EVT tester).

Inspection of balls on the Ball Scanner Wet is carried out while they are submerged in a special liquid based on mineral oil. Thanks to inspection in liquid the balls do not need to be dried after cleaning before the inspection which saves time and operating costs. Another advantage of wet inspection is that with a suitably selected operating liquid or additive, the balls can already be conserved during the inspection process. Testing in liquid also allows more accurate measurement by the EOT tester thanks to the better optical properties of liquid compared to the open air and the reduction of dirt on the surface of the ball.

KROB SCANNERS Ball Scanners have more than 25 years of tradition in the quality assurance inspection of bearing balls. Since 2008 our „Wet“ series has offered a wide range of functions and usage with the guarantee of reliability. Thanks to their advantages, the „Wet“ series machines have gained an irreplacable position in the quality assurance inspection of bearing balls for leading producers around the world.
