FAQs

1. What is the difference between 6302 and 6202 bearings?
6302 bearings have deep raceways and higher load capacity compared to 6202 bearings, which have shallower raceways and lower load capacity.

2. What is the maximum speed that a 6302 bearing can handle?
The limiting speed for a 6302 bearing is typically around 22,000 rpm.

3. How long do 6302 bearings last?
With proper lubrication and maintenance, 6302 bearings can last for several years or even decades.

4. Can 6302 bearings be used in extreme environments?
Shielded or sealed 6302 bearings can be used in wet or dusty environments, while open bearings are suitable for clean and dry conditions.

5. Where can I buy 6302 bearings?
6302 bearings are widely available from bearing suppliers, online retailers, and hardware stores.

6. What is the approximate price of a 6302 bearing?
The price of a 6302 bearing can vary depending on its size, type, and supplier, but it typically ranges from $10 to $20.

Conclusion

6302 bearings are versatile and widely-used components in a variety of industrial and automotive applications. Their high load-carrying capacity, low friction, and high speed capabilities make them a popular choice for demanding applications. By understanding their features, specifications, applications, and maintenance tips, engineers and technicians can ensure the optimal performance and longevity of these bearings.
