6203 bearings are widely used in various industries due to their high precision, durability, and load-bearing capacity. Understanding their specifications is crucial for selecting the right bearing for your application. This in-depth guide will provide a comprehensive overview of 6203 bearing specifications, including dimensions, tolerances, load ratings, materials, and applications.
Dimension | Value | Tolerance |
---|---|---|
Bore Diameter | 17 mm | h6 |
Outer Diameter | 47 mm | h6 |
Width | 14 mm | - |
Load Type | Dynamic Load Rating (C) | Static Load Rating (C0) |
---|---|---|
Radial | 3.9 kN | 1.9 kN |
Axial | 1.5 kN | 1.0 kN |
6203 bearings are manufactured to ABEC 1 precision standards, ensuring low noise, minimal vibration, and smooth operation.
The maximum operating speed for 6203 bearings is typically 12,000 rpm. However, this value can vary depending on the specific application and operating conditions.
6203 bearings are typically pre-lubricated with a high-quality grease, providing long-term lubrication without the need for frequent maintenance.
6203 bearings are versatile and find applications in various industries, including:
Story 1: The Overzealous Engineer
A young engineer was tasked with designing a high-performance gearbox for an industrial machine. In his enthusiastic pursuit of precision, he specified 6203 bearings with ABEC 7 precision. However, during testing, the gearbox experienced excessive noise and vibration. After much troubleshooting, it was discovered that the high-precision bearings were causing the issue. The engineer had overlooked the fact that the gearbox's operating environment was not clean enough for such high-precision bearings.
What we learn: It's important to consider the operating environment when selecting bearing precision levels.
Story 2: The Grease Impasse
A technician was servicing a conveyor line when he noticed a 6203 bearing overheating. Upon inspection, it was discovered that the bearing was not lubricated. The technician assumed that the bearing was pre-lubricated and had not checked its lubrication status. As a result, the bearing seized and damaged the conveyor's shaft.
What we learn: Always check the lubrication status of bearings before installing them.
Story 3: The Bearing Swap
A maintenance crew replaced a worn-out 6203 bearing in an electric motor. However, they mistakenly installed a bearing with a slightly larger bore diameter. Initially, the motor operated smoothly. However, after a few days, the bearing began to wobble and make a loud grinding noise. The motor eventually failed due to the misaligned bearing.
What we learn: Always verify the dimensions and compatibility of bearings before installing them.

Understanding the specifications of 6203 bearings is essential for selecting the right bearing for your application. By considering factors such as load capacity, precision, speed, lubrication, and dimensions, you can ensure optimal performance and longevity of your equipment. Remember to consult with bearing manufacturers for expert guidance and to implement effective strategies and techniques to get the most out of 6203 bearings.
