## Who it’s for

- You ride speed skates, compete in marathons or train a lot, and low friction matters to you.
- Your steel bearings quickly lose their smoothness and you are looking for a set that will last longer.
- You have skates with 608 bearings — Rollerblade, FR Skates, Powerslide, K2, Seba, Roces or others.

## When to choose something else

- You want bearings that you rinse with water and do not lubricate — the full ceramic [Stelior Pro White Ceramic](https://bogdanca.pl/en/stelior-pro-white-ceramic-racing-bearings-16-pcs.html) are like that.

## Key features

- **Si3N4 ceramic balls** — Silicon nitride is harder than steel and resistant to corrosion: the balls offer less resistance and wear more slowly.
- **GCR15 rings with a titanium coating** — The chrome steel raceways work as in classic steel bearings, and the titanium coating gives this version its colour.
- **RS rubber shields** — They are easy to remove and put back, so cleaning and lubricating takes a moment; you choose the shield colour when ordering.
- **Choice of lubrication** — Bones Speed Cream for maximum speed, Rollerblade Dry Fluid as a compromise between speed and protection, or Stelior Ceramic Grease when you skate in difficult conditions.
- **Set of 16** — Two bearings for each of the eight wheels; each wheel also needs one spacer.

## Questions and answers

### How do Black Ceramic differ from White Ceramic?

In the ball material. Black Ceramic have silicon nitride (Si3N4) balls — harder, with less friction and more durable; White Ceramic have zirconium oxide (ZrO2) balls, also corrosion-resistant, but less hard.

### Are they better than Twincam ILQ-9 and ABEC 9 bearings?

Yes, Stelior claims lower friction, harder balls and a longer life than in Twincam ILQ and ABEC 9 bearings. The ABEC scale describes only manufacturing tolerances, not how a bearing behaves in skates.

### How many spacers do I need?

Eight, one per wheel: each wheel takes 2 bearings and 1 spacer. We will match Stelior spacers to the cores of your wheels as part of the “Wheel core measurement and spacer selection” service.

### Can they be washed with water?

No. Clean the steel rings with extraction naphtha or paraffin, and lubricate the bearings after cleaning.

### Do they fit my skates?

Yes, if you have 608 bearings (8 × 22 × 7 mm). They fit Rollerblade, FR Skates, Powerslide, K2, Seba, Roces, USD, Micro, Bont and other models with this standard.
