Everything You Need to Know About 6203 Bearing Dimensions and Their Uses

Bearings play a critical role in various mechanical systems, ensuring smooth operation, reducing friction, and improving performance. Among the wide variety of bearings available, the 6203 bearing stands out as one of the most commonly used options. Understanding its dimensions and applications is essential for selecting the right bearing for your needs.

What is a 6203 Bearing?

A6203 bearing is a type of deep groove ball bearing, which is known for its ability to handle both radial and axial loads. It is designed with a single row of balls, making it compact and reliable for a wide range of applications. The "6203" designation refers to the bearing's size and type: "6" signifies a deep groove ball bearing, and "203" is the specific size code.

6203 Bearing Dimensions

The 6203 bearing is a standard-size bearing, with the following typical dimensions:

• Inner Diameter (ID): 17 mm
• Outer Diameter (OD): 40 mm
• Width (B): 12 mm

These dimensions make the 6203 bearing highly versatile and suitable for a variety of machinery. The 6203 bearing can be found in everything from household appliances to automotive applications, where reliable and long-lasting performance is needed.

Key Features of 6203 Bearings
