Sizes of Skateboard Bearings: A Comprehensive Guide
Sizes of Skateboard Bearings: A Comprehensive Guide
Skateboard bearings play a crucial role in determining the performance and longevity of your skateboard. Understanding their size is essential for optimal riding experience.
Standard Sizing
Most skateboard bearings follow a standard size system:
| Bearing Size | Inner Diameter (mm) | Outer Diameter (mm) | Width (mm) |
|---|---|---|---|
| 608 | 8 | 22 | 7 |
| 6900 | 10 | 22 | 12 |
| 6001 | 12 | 28 | 8 |
| 608zz | 8 | 22 | 8 |
Custom Sizes
Some manufacturers offer custom-sized bearings for specific applications:
| Bearing Size | Inner Diameter (mm) | Outer Diameter (mm) | Width (mm) |
|---|---|---|---|
| Mini | 6 | 19 | 6 |
| Micro | 5 | 16 | 5 |
| Oversized | 15 | 32 | 9 |
Choosing the Right Size
The correct size of bearing depends on the wheel size and axle diameter:
| Wheel Size (mm) | Axle Diameter (mm) | Bearing Size |
|---|---|---|
| 52-54 | 6 | 608 |
| 56-58 | 8 | 608 |
| 60-62 | 10 | 6900 |
| 64-66 | 12 | 6001 |
Success Stories
- Tony Hawk: Used custom-sized bearings for improved speed and maneuverability.
- Nyjah Huston: Endorsed bearings designed for high-impact riding.
- Stephanie Gilmore: Chose smaller bearings for increased responsiveness.
Effective Strategies
- Use the correct size: Avoid performance issues by pairing bearings with the appropriate wheel and axle sizes.
- Clean bearings regularly: Extend bearing life by removing dirt and debris with a bearing cleaner.
- Lubricate bearings periodically: Improve performance and reduce friction by applying bearing lube.
Common Mistakes to Avoid
- Overtightening bearings: Can damage bearings and impair performance.
- Using incompatible bearings: Mixing different bearing sizes can result in uneven wear and poor handling.
- Riding with dirty bearings: Can lead to premature failure and reduced speed.
Challenges and Limitations
- Custom bearings: May be more expensive and difficult to source.
- Bearing wear: All bearings eventually wear out, requiring replacement.
- Environmental impact: Bearings can contribute to plastic pollution if not disposed of properly.
Pros and Cons of Different Sizes
| Size | Pros | Cons |
|---|---|---|
| Small (Mini/Micro) | Lightweight, responsive | Less durable, less speed |
| Standard (608) | Versatile, cost-effective | May not be optimal for specific applications |
| Large (6900/6001) | Increased speed, stability | Heavier, more expensive |
| Custom | Tailored to specific needs | Difficult to find, more expensive |
Making the Right Choice
Consider the following factors when choosing size of a skateboard bearing:
- Wheel and axle size
- Riding style and preferences
- Budget and availability
By understanding the sizes of skateboard bearings and applying these strategies, you can optimize your skateboard's performance and enjoy a smooth and enjoyable ride.
