The 6203 bearing size is a popular choice for various industrial applications due to its versatility and durability. This guide aims to provide a comprehensive overview of the 6203 bearing size, including its dimensions, load capacity, and applications. By understanding the specifications and benefits of this bearing size, you can make informed decisions for your project requirements.
The 6203 bearing is a single-row, deep groove ball bearing with a bore diameter of 17 mm, an outer diameter of 40 mm, and a width of 12 mm. It has a radial load rating of 10.8 kN and a dynamic load rating of 23.6 kN. The bearing is made of high-quality steel for strength and durability and is sealed to protect against contaminants.
| Parameter | Value |
|---|---|
| Bore Diameter | 17 mm |
| Outer Diameter | 40 mm |
| Width | 12 mm |
| Radial Load Rating | 10.8 kN |
| Dynamic Load Rating | 23.6 kN |
| Material | High-Quality Steel |
The 6203 bearing is suitable for applications with moderate loads and high speeds. Its deep-groove design allows for radial and axial loads, making it ideal for use in shafts, pulleys, and other rotating components. The bearing can operate at speeds up to 10,000 rpm, making it suitable for high-speed machinery.
Industries that commonly use the 6203 bearing size include:
The 6203 bearing size is similar to the 6202 bearing size, but it has a larger bore diameter and can withstand higher loads. It is also comparable to the 6204 bearing size, but it is smaller and has a lower load capacity.
| Bearing Size | Bore Diameter (mm) | Radial Load Rating (kN) |
|---|---|---|
| 6202 | 15 | 8.2 |
| 6203 | 17 | 10.8 |
| 6204 | 20 | 13.5 |
Story 1:
A maintenance technician was installing a 6203 bearing on a high-speed motor. He accidentally dropped the bearing, damaging its seal. As a result, the motor failed prematurely due to contamination.
Lesson: Handle bearings with care during installation and maintenance to avoid damage.
Story 2:
An engineer designed a machine with a 6202 bearing. However, during testing, the bearing failed due to excessive loads. The engineer realized that a 6203 bearing with a higher load capacity was required for the application.
Lesson: Consider the specific load requirements of your application and select the appropriate bearing size to avoid failures.
Story 3:
A factory manager noticed that the 6203 bearings on their machines were failing frequently. They contacted a bearing supplier, who recommended a different lubrication strategy. The new lubrication method extended the bearing life significantly, reducing downtime and maintenance costs.
Lesson: Proper lubrication can significantly extend the life of bearings, resulting in cost savings and improved efficiency.
A 6204 bearing has a larger bore diameter and higher radial load rating than a 6203 bearing.
No, the 6203 bearing has a larger bore diameter, so it will not fit in the same housing as a 6202 bearing.
High-quality grease or oil specifically designed for high-speed bearings is recommended to extend their performance.
Regular inspection intervals will depend on the specific operating conditions. However, it is generally recommended to inspect bearings quarterly or more frequently in harsh environments.
Minor damage, such as surface scratches, may be repairable. However, significant damage typically requires replacing the bearing.
6203 bearings are widely available from bearing suppliers, authorized distributors, and online retailers.
The lifespan of a 6203 bearing will vary depending on the operating conditions, maintenance practices, and environmental factors. However, with proper maintenance, a 6203 bearing can last for several years.
Yes, 6203 bearings with special seals and lubricants are available for vacuum applications.
