Frequently Asked Questions (FAQs)

1. What is the life expectancy of a 6004 bearing?
   - With proper maintenance, a 6004 bearing can have a lifespan of up to 10 years or longer.

2. How do I identify a 6004 bearing?
   - 6004 bearings are typically marked with the designation "6004" or "6004-2RS" (where "2RS" indicates the sealing type).

3. Can I replace a 6004 bearing myself?
   - Replacing a 6004 bearing requires specialized tools and knowledge. It is recommended to consult a qualified mechanic or bearing specialist for assistance.

4. What is the difference between a 6004 bearing and a 6204 bearing?
   - The 6004 and 6204 bearings have the same inner and outer diameters, but the 6204 bearing has a wider width (15 mm instead of 12 mm). This makes it suitable for applications with higher axial loads.

5. How often should I lubricate a 6004 bearing?
   - The frequency of lubrication depends on the operating conditions. As a general rule, bearings should be lubricated every 3-6 months or more frequently if exposed to harsh environments.

6. What type of grease should I use for a 6004 bearing?
   - Use a high-quality, bearing-specific grease that is compatible with the bearing's operating conditions.

7. How do I know when to replace a 6004 bearing?
   - Replace bearings when they show signs of excessive wear, noise, vibration, or other performance issues.

   

8. Where can I buy 6004 bearings?
   - 6004 bearings are available from bearing distributors, industrial suppliers, and online retailers.
