Integrated Spacer Technology
No More Traditional Bearing Spacers
The standout feature of the Rollerblade Hydrogen SK-9 Bearings is the exclusive Integrated Spacer System.
Each bearing includes a built-in half spacer, so when both bearings are installed into the wheel, they automatically create the correct spacing without requiring separate bearing spacers or additional hardware.
This innovative design provides several important advantages:
- No separate spacers required
- Faster and easier wheel assembly
- Perfect bearing alignment
- Reduced rolling friction
- Lower overall weight
- Improved rotational stability
- More efficient power transfer
By eliminating loose spacers, installation becomes quicker while ensuring consistently precise bearing alignment.
