Scooter and Skateboard bearings are the same size and so can be used in either scooter wheels or skateboard wheels. Bearings that have been manufactured for skateboards come in packs of 8 whereas bearings manufactured for scooters come in packs of 4. Some bearings have an ABEC rating and some do not. Just because a bearing does not have an ABEC rating does not mean the bearing is rubbish, infact our best selling bearings are Bones Reds and they do not rate their bearings! If you are on a budget or just need single bearings then check out our NMB bearings as they are only £1.00 each and great quality. If you are fitting your bearings into Metal Core Scooter Wheels then check out our guide - 'How to fit Scooter Bearings'.
