Specifications

6203 bearings have the following specifications:

• Bore diameter: 17 mm
• Outer diameter: 40 mm
• Width: 12 mm
• Load capacity: 5.25 kN (dynamic), 2.91 kN (static)
• Speed limit: 10,000 rpm

Applications

6203 bearings are used in a wide range of applications, including:

• Automotive: Transmissions, differentials, and wheels
• Industrial: Pumps, fans, and compressors
• Agricultural: Tractors and other farm equipment
• Household: Washing machines, dryers, and vacuum cleaners

Maintenance

6203 bearings require regular maintenance to ensure optimal performance and extend their service life. Maintenance tasks include:

• Lubrication: 6203 bearings should be lubricated regularly with a high-quality grease. The frequency of lubrication will depend on the operating conditions.
• Inspection: Bearings should be inspected regularly for signs of wear or damage. If any damage is found, the bearings should be replaced.
• Replacement: Bearings should be replaced when they show signs of wear or damage, or if they have reached their end of life.

Tips and Tricks

Here are a few tips and tricks for using 6203 bearings:

• Use the right lubricant: The type of lubricant you use will depend on the operating conditions. For high-speed applications, a high-temperature grease is recommended.
• Inspect bearings regularly: Inspect bearings regularly for signs of wear or damage. This will help you catch problems early and prevent costly breakdowns.
• Replace bearings when necessary: Bearings should be replaced when they show signs of wear or damage, or if they have reached their end of life.

How to Step-by-Step Approach

Here is a step-by-step approach to installing a 6203 bearing:

1. Clean the bearing seat. The bearing seat is the surface on which the bearing will be installed. Make sure the seat is clean and free of any debris.
2. Apply a thin layer of grease to the bearing seat. This will help the bearing to slide into place and prevent it from seizing.
3. Place the bearing on the seat. Align the bearing carefully and press it into place.
4. Secure the bearing. Use a retaining ring or other method to secure the bearing in place.

Compare Pros and Cons

Pros:

• High load capacity
• Long service life
• Simple design
• Easy to maintain

Cons:

• Not suitable for high-speed applications
• Can be noisy

FAQs

Q: What is the difference between a 6203 bearing and a 6204 bearing?
A: 6203 bearings have a bore diameter of 17 mm, while 6204 bearings have a bore diameter of 20 mm.

Q: What is the life expectancy of a 6203 bearing?
A: The life expectancy of a 6203 bearing will depend on the operating conditions. However, under normal operating conditions, a 6203 bearing can have a life expectancy of 10 years or more.

Q: Can I use a 6203 bearing in a high-speed application?
A: No, 6203 bearings are not suitable for high-speed applications. For high-speed applications, a bearing with a higher speed limit is recommended.
