Questions
Why ceramic balls?
Ceramic takes more heat than steel and is stronger, so the bearing lasts longer and holds up better to hard knocks.
Why greased?
Grease carries heat away and needs less upkeep than oil. It spins a little less freely in your hand, which doesn't matter once your weight is on the skate.
How many do I need?
Two bearings go in each wheel. A 16 pack fills 8 wheels, one pair of quad skates or a pair of 4-wheel inline skates.
Will they fit my skates?
They fit 8mm axles, as on most skates. There is no 7mm Qube Ceramic.
