Clean your bearings in ten minutes

Your board rolls slower every month and you're convinced the bearings are dying. They're not. They're dirty. Ten minutes and €5 of solvent brings back the day-one roll — no new bearings required.

01Why your board rolls slowly

Bearings are sealed races of steel balls running in a thin film of lubricating oil. Dust, grit, rainwater and sweat slowly contaminate that film. Once the oil turns to grinding paste, the balls drag instead of roll. You feel it as 20–30% slower push.

Replacing the bearings "fixes" it — but so does cleaning them. Bones Reds (€25/set) will last ten years if you clean them every three months. They'll last four months if you don't.

Every "my bearings are broken" complaint that walks through the door is a cleaning problem. New bearings feel great because they're clean, not because they're new.

02The five-euro kit

• A glass jar with a screw lid (any 250ml jar).
• Citrus cleaner (€3 — white-spirit substitute; available at any hardware shop).
• A paper towel or clean rag.
• A pin or needle (for shield removal).
• A skate-specific lubricant (Bones Speed Cream €6, or a 3-in-1 machine oil €2).
• A T-tool or axle nut tool.

03Removing the bearings

Undo the axle nut, pull the wheel off the truck. To pop the bearings out: slide the wheel back onto the truck axle about halfway and lever the wheel sideways — the outer bearing pops out. Repeat for the inner.

Place all eight bearings on the rag. Using the pin, slide it under the rubber shield and prise outward — the shield lifts clean off. Keep the shields together; they go back on after cleaning.

04Cleaning

Drop all eight bearings into the glass jar. Pour enough citrus cleaner to cover them completely. Seal the lid. Shake for 60 seconds. You'll see the solvent go dark — that's the contaminated oil coming out.

Pour off the dirty solvent. Add fresh solvent. Shake for 60 seconds again. Spin a bearing between finger and thumb — if it still feels gritty, repeat a third time. Most bearings are clean after the second rinse.

Tip the bearings onto the rag and roll them gently to dry. Don't use compressed air — it spins the bearing above its rated speed and damages the cage.

05Oiling and reseating

Two drops of Speed Cream (or 3-in-1 oil) per bearing, applied into the exposed races. Spin the bearing with a finger to distribute the oil. Replace the rubber shields — press them back in with a fingernail.

Reseat the bearings into the wheels: place one bearing on the truck axle as a seat, press the wheel down over it until it clicks flush. Flip the wheel and seat the second bearing the same way. Install on the truck, tighten the axle nut, back off a quarter turn.

06How often to do this

• Every 3 months for daily skaters in dry conditions.
• Every 6 weeks for daily skaters in wet / winter conditions.
• After any ride in the rain — clean and oil the next day, always.
• On feel: if your push drops off a visible amount, it's time.
