Industry introduction

Bearing parts in the actual production process due to the inherent defects of the material itself, processing scratches, heat treatment differences and other factors may produce cracks and other defects, thereby accelerating bearing damage and reducing service life. Therefore, non-destructive testing to detect cracks and other defects in the production process is an important link to control the quality of bearing products.

The limitation of traditional magnetic particle detection technology: slow detection speed, poor stability (manual intervention), low degree of automation, high energy consumption of equipment, pollution emission (auxiliary agent required) and other shortcomings.

Eddy current testing technology for bearing testing has the following advantages: fast detection speed, no coupling or auxiliary agent, no manual intervention, automatic loading and unloading, automatic sorting, low energy consumption of equipment, pollution-free discharge, etc., which can effectively ensure the accuracy and stability of non-destructive testing, and has great advantages. In the quality testing of bearing parts, magnetic particle detection has become an inevitable trend.

Application case: bearing ring

Bearing ring is an important part of the bearing, in the production process due to materials and processing factors may produce cracks and defects, will have a serious impact on the quality of bearing products, so the bearing manufacturers are actively taking measures to solve this problem.

Eddy current detection is very sensitive to surface cracks of bearing rings. The eddy current bearing flaw detection equipment developed by Cangxin NDT has the advantages of high detection efficiency, good accuracy and stability, high degree of automation, low cost, and the detection speed can reach 1-3 seconds/piece, which has a very high cost performance.
