Ultrasonic Testing of Three Pivot Bearings in Aircraft Engine

The internal defects of three pivot bearings in aero engine shall lead to inner metal rail off.Through the analysis of the structure of the bearing member and the related experiments it was found that the testing of the bearings needed for corresponding detection technique and reference to acceptance criteria.Using a special probe and test block,and using ultrasonic immersion focusing detection technology of high sensitivity can effectively guarantee the detection of defects in the inner portion of the bearing member.
