Fits wheels on 8mm axles, as on almost every inline skate.
Uniq Swiss bearings are skate bearings from Uniq, the line designed by Doug Glass. They have precision steel balls, double honed races and grooves made deeper for skating. A 16 pack fills a pair of 4-wheel skates.
Bearing features
Precision steel balls: Steel balls made to tight tolerances.
Double honed races: The inner and outer races are honed twice for a smooth roll.
Deeper grooves: Made for the side loads of skating.
Nylon 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.
Made for: Speed, fitness and quad skaters who want a Swiss bearing they can clean.
Questions
Why a shield on only one side?
The open side gives you easy access to clean and oil the bearing. The non-contact shield keeps dirt out without rubbing.
Swiss or ceramic?
The Swiss has steel balls. The Uniq Ceramic has ceramic balls made in Japan and costs more.
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.
