# Rollerblade Junior 6 mm aluminium reducing spacers (8 pcs)

The Rollerblade Junior 6 mm reducing spacers are a set of 8 aluminium spacers for skates with 6 mm axles, i.e. M6 bolts — mainly kids' skates such as the Microblade, Spitfire, Arrow or Thunder. The projecting ends reduce the 608 bearing bore from 8 to 6 mm, and the spacer keeps the bearings at a fixed distance, so a tightly fastened axle does not squeeze them.

## Who it’s for

- Your child skates on Rollerblade Microblade, Spitfire, Arrow or Thunder skates and the spacers went missing when you changed the wheels or bearings.
- You are buying new 608 bearings for skates with 6 mm axles and need spacers that fit their bore to the axle diameter.
- You have adult skates on M6 bolts and need a set of spacers as a replacement.

## When to choose something else

- The axles on your skates are 8 mm — these spacers will not accept them; see [spacers and axles](https://bogdanca.pl/en/wheels-and-bearings/spacers-and-axles).

## Key features

- **Bore reduced from 8 to 6 mm** — The projecting ends of the spacer go into the 608 bearing and fit its bore to the thinner axle, so the wheel sits on the axle without play.
- **Fixed distance between bearings** — You can tighten the axle bolt firmly without squeezing the bearings, which would increase rolling resistance.
- **Fit any 608 bearing** — The bearing class does not matter — ABEC, ILQ, SG or Twincam; what counts is the 608 standard.
- **Aluminium** — A metal spacer does not deform under the pressure of the axle, so it protects the bearings and wheel cores for longer.
- **Set of 8** — One spacer per wheel — the set is enough for a pair of four-wheel skates.

## Questions and answers

### Will these spacers fit my skates?

Yes, if your skates have 6 mm axles (M6 bolts) and 608 bearings. That is the case with, among others, the kids' Rollerblade Microblade, Spitfire, Arrow and Thunder; with another model, measure the axle or bring a wheel to our shop in Poznań or Wrocław.

### Will they fit my ABEC or ILQ bearings?

Yes. They fit any 608 bearing, whatever the class: ABEC, ILQ, SG or Twincam.

### How many spacers do I need for a pair of skates?

One per wheel. A set of 8 is enough for a pair of four-wheel skates.

### What is the spacer in the wheel for?

It keeps the bearings at a fixed distance. Without it a tightened axle squeezes the bearings, the wheel turns heavily, and the bearings and core wear out faster.

### Can I return the spacers?

Yes, you have 14 days to withdraw from the contract (return) without giving a reason. The buyer covers the return shipping.
