Good bearing care is a few sensible checks, not a complicated ritual. Keep grit and moisture under control, assemble the wheel correctly and pay attention when the way it turns changes.
After a session
Wipe down dusty or damp wheels and store the board somewhere dry and ventilated. Do not put a wet setup into a closed bag. If the wheels have been exposed to water, inspect them once they are dry before riding again.
When a wheel feels different
Spin it by hand and check for rubbing, binding, loose hardware or a bearing that feels rough. Make one adjustment at a time. If the bearing is dirty but otherwise healthy, follow a suitable cleaning method, dry it fully and use compatible lubricant according to its instructions.
Know when to replace
Cleaning cannot repair a cracked, badly corroded or worn bearing. If it remains rough or sticks after appropriate care, replace it rather than relying on it during a session.
