FAQs

1. What is the difference between 6206RS and 6206-2RS bearings?
   - The 6206-2RS bearing has two contact seals on both sides, providing enhanced protection against contamination compared to the single contact seal in the 6206RS bearing.

2. What is the recommended lubrication interval for the 6206RS bearing?
   - The lubrication interval varies depending on the operating conditions. As a general guideline, lubricate the bearing every 6-12 months or more frequently in harsh environments.

   

3. How do I determine the equivalent dynamic load for a bearing?
   - Calculate the equivalent dynamic load (P) using the formula: P = F_r x Y_r + F_a x Y_a, where F_r and F_a are radial and axial forces, respectively, and Y_r and Y_a are application factors.

4. What precautions should I take when storing 6206RS bearings?
   - Store bearings in a cool, dry, and clean environment. Prevent exposure to moisture, corrosive chemicals, and excessive heat.

5. How can I extend the service life of a 6206RS bearing?
   - Follow proper installation and maintenance guidelines, use high-quality bearings, monitor operating conditions, and address any issues promptly.

6. What is the typical radial internal clearance for a 6206RS bearing?
   - The radial internal clearance for a 6206RS bearing is typically C3, which indicates a clearance of 0.13-0.23 mm.

7. Can I use a 6206RS bearing in a submerged application?
