When replacing roller bearings, it's essential to understand the right choices and avoid common mistakes that can lead to premature failure. Here are some key points to consider.
**Common Mistakes Beginners Make**
1. **Choosing the Wrong Type of Bearing**
Many beginners think they can just pick a bearing based on its appearance or reputation. For example, some people may be attracted to ceramic bearings because they look cool, but these aren't always suitable for all applications. Ceramic bearings may offer less friction and higher speed, but they are not as durable in certain conditions and can fail quickly if not used properly.
2. **Misunderstanding Bearing Grades**
A common misconception is that a higher grade like -7 is always better than -5. However, this isn't necessarily true. The ABEC rating only refers to the precision of the bearing, not its performance. In reality, a high-quality -5 bearing with better materials and lubrication can outperform a lower-grade -7 one.
3. **Using the Wrong Materials for Cleaning**
Some people use harsh chemicals like WD-40 or gasoline to clean bearings, thinking it will make them cleaner. However, these substances can damage the bearing’s internal components, such as the races and balls, leading to early wear and failure.
4. **Assuming Ceramic Bearings Are Universal**
Ceramic bearings are not suitable for every application. They work well in specific scenarios, such as high-speed skating, but are not ideal for all types of skateboarding or sports. Using them where they don’t belong can result in damage and poor performance.
5. **Mixing Industrial Bearings with Roller Bearings**
Industrial bearings are often mistaken for roller bearings. While industrial bearings are strong and durable, they are not designed for the same purposes as roller bearings. Using them in place of proper roller bearings can lead to inefficiency and mechanical issues.
6. **Ignoring Clearance and Lubrication Needs**
Proper clearance and lubrication are crucial for bearing performance. Choosing the wrong clearance or using inappropriate lubricants can cause excessive heat, wear, and eventual failure.
**Choosing the Right Bearing for Your Needs**
- For general street skating, ABEC-7 bearings are usually sufficient.
- For aggressive skating (FSK players), ILQ-9 iron-capped bearings with steel brackets are recommended.
- For flatland skaters, ILQ-9 iron-capped bearings are ideal, but too fast bearings may not suit certain tricks.
- For limit skaters, ABEC-5 or even ABEC-3 bearings from foreign brands can be great options.
- For speed skating, single-sided dustproof ceramic bearings are a good choice.

If you're looking to improve your skating experience, take the time to understand which bearings are best suited for your style. Always ensure you're using the correct tools and techniques when replacing or maintaining your bearings. With the right knowledge, you can extend the life of your equipment and enjoy better performance.
