Scooter Bearings

Most scooters use 608‑size bearings with an 8 mm inner diameter. Some brands offer high‑precision or ceramic bearings for improved performance.

ABEC ratings (1, 3, 5, 7, 9) measure manufacturing tolerances. Higher ABEC bearings spin more smoothly at high speeds. However, many scooter bearings use different rating systems (like ILQ) designed for the loads and vibrations of freestyle riding.

They replace steel balls with ceramic ones, reducing friction and improving longevity. Ceramic bearings run smoother and resist corrosion but cost significantly more than steel versions.

Clean bearings every few months or sooner if you ride in wet or dusty conditions. Remove them, soak in a bearing cleaner or isopropyl alcohol, dry thoroughly and reapply lubricant.

Press the bearings evenly into the wheel hubs using a bearing press or by hand with an axle bolt. Ensure they’re fully seated and that the spacer is correctly aligned between bearings.

Noisy bearings may be dirty, dry or damaged. Cleaning and lubricating them often resolves the issue. If the noise persists, replace the bearings to avoid damage to your wheels.

Most 608‑size bearings fit standard scooter wheels. Check the wheel bore and axle diameter to ensure compatibility, especially when using older or non‑standard components.

Use bearing‑specific lubricants or light oils designed for high‑speed applications. Avoid thick grease, which can slow bearings down.
