Anatomy of a 6203 Bearing

A 6203 bearing is a deep-groove ball bearing characterized by its single row of ball elements held between two concentric rings known as the inner race and outer race. These components are separated by a cage that prevents the balls from rubbing against each other. The bearing's dimensions adhere to international standards, making it interchangeable with similar products.

Key Dimensions:

• Bore: 17 mm
• Outer Diameter: 40 mm
• Width: 12 mm
