The Roll-Line Speed Max Abec 9 Bearings are specifically designed and manufactured for high level competitive Roller Skating of all types and styles. The Speed Max Abec 9 Bearings are free rolling with minimal radial play which evenly distributes the load across the eight balls for optimal roll and thrust. The Speed Max have a reinforced steel casing and are sealed airtight to prevent the entry of dust.
Be sure you identify which size Axles you have and which size (7mm or 8mm) Bearings are needed. NOTE: Speed MAX is only available in 7mm.
