Bearing Condition Tester for Wheelset Bearings
This bearing condition test jig is installed at a depot workshop to detect bearing conditions when the bearings are fixed on the wheelset. The jig rotates the bearing cup to generate relative movement between bearing components, which are then analyzed for defects.

Overview
Bearing Condition Diagnostic System
This specialized test jig is designed for depot workshop environments to assess the condition of bearings while they remain fixed on the wheelset. By rotating the bearing cup to generate vibration signals, the system utilizes advanced algorithms to detect defects such as spalls and scratches on the cup, cone, and rollers. It provides a comprehensive, non-destructive diagnostic solution that enhances maintenance efficiency and ensures the safety of rolling stock operations.
