This comprehensive guide delves into the intricacies of 6203 bearing size, providing valuable insights and practical knowledge for engineers, maintenance personnel, and anyone involved in the selection and use of bearings.

What is a 6203 Bearing?

A 6203 bearing is a single-row deep-groove ball bearing designated by the international bearing numbering system. It comprises an inner ring, an outer ring, a cage, and a set of deep-groove ball elements. The 6203 designation conforms to the following structure:

Where:

• Prefix (6): Indicates a deep-groove ball bearing
• First Number (2): Represents the bearing's series (in this case, light series)
• Second Number (03): Denotes the bearing's bore diameter (in this case, 17 mm)
• Suffix (-): No suffix indicates a standard bearing with no special modifications
