Miniature Bearing Inspection Machine

Overview

Our Miniature Bearing Inspection Machine is a dedicated high-speed vision inspection solution developed for small and precision bearings used in demanding industries such as automotive, robotics, and electronics.
Using AI-powered image analysis, the system detects surface and structural defects invisible to the human eye — ensuring every bearing meets stringent quality standards.

The system performs comprehensive inspection on each bearing's outer ring, inner ring, end face, cage, and dust groove, including:

• Outer Ring Defects - Bright surface (polishing issue), Vibration marks or texture defects, Material waste or cracks, Dents and impact marks, Oversized or undersized chamfer.
• Inner Ring Defects - Missing or irregular chamfer sections, Chamfer size too large or too small
• End Face Defects - Scratches, rust spots, dents, Material waste on surface, Edge chipping or collision marks
• Internal Assembly Defects - Missing balls, Cage bending or deformation
• Dust Groove Defects - Notches, missing edges, Chamfer too large or too small

Key Features
