Fits wheels on 8mm axles, as on almost every inline skate.
Uniq Ceramic bearings are skate bearings from Uniq, the line designed by Doug Glass. They have precision ceramic balls made in Japan, double honed races and grooves made deeper for skating, and a bottle of speed oil comes with them. A 16 pack fills a pair of 4-wheel skates.
Bearing features
Ceramic balls made in Japan: Precision ceramic balls.
Double honed races: The inner and outer races are honed twice for a smooth roll.
Deeper grooves: Made for the side loads of skating.
Delrin retainers: Hold the balls in place.
Shield on one side: A non-contact rubber shield on one side, with the other side open, so they are easy to clean and oil.
Speed oil included: A .17 oz bottle of light speed oil comes in the tin.
Made for: Racers and fitness skaters who want ceramic bearings.
Questions
Does it come with oil?
Yes. A .17 oz bottle of light speed oil comes in the tin.
Ceramic or Swiss?
The ceramic has ceramic balls made in Japan and Delrin retainers. The Uniq Swiss has steel balls and costs less.
How many do I need?
Two bearings go in each wheel. A 16 pack fills 8 wheels, a pair of 4-wheel skates. A pair of 3-wheel skates takes 12, so 4 are left as spares.
Will they fit my wheels?
Yes, if your skates have 8mm axles, as almost all inline skates and most quad skates do. These are standard 608 bearings.
