Wheels and bearings — page 4

What to replace to make your skates roll better

Start with a diagnosis, because new bearings won’t help worn polyurethane, and new wheels won’t help seized bearings.

Symptom	Most common cause	Where to look
Wheels worn down on one side, skates slide on turns	worn wheels, no rotation	inline skate wheels
Grinding, rust, drag after skating in the rain	dirty or rusty bearings	bearings
Wheel slows down after tightening the axle or wobbles sideways	wrong spacer length	spacers and axles

Three numbers you need to know

Wheel diameter in millimetres — no bigger than the maximum for your frame.
Hardness on the A scale — 82A–83A are softer, grippier wheels, 85A all-round, 88A hard and durable.
Bearing size — the standard in inline skates is 608, with an 8 mm bore.

How to choose without mistakes

You’ll find the maximum wheel diameter in the skate specifications. If your skates come from another shop, give us the model and year — we’ll check what fits. Two guides cover the rules: how to choose inline skate wheels and inline skate bearings: ABEC, ILQ, Swiss.

Frequently asked questions

Which wheels fit my skates?

Any with a diameter no bigger than the maximum for your frame. You’ll find this value in the skate specifications, and often on the frame itself.

Are bearings with a higher ABEC rating faster?

Not directly. ABEC describes manufacturing tolerance, and how a bearing rolls also depends on the steel, the lubricant and the seals.

How many bearings do I need for my skates?

Two per wheel: 16 for skates with eight wheels and 12 for three-wheel skates.

Are wheels sold with bearings?

It depends on the set — check the product description. Bearings from old wheels can usually be transferred if they spin quietly and without resistance.
