Bones Swiss Ceramic Bearings

Bones Swiss Ceramic Bearings

Made in Switzerland with ceramic balls. The top of the Bones range.

Bones Swiss Ceramics are the top of the Bones bearing range. If you want the fastest, longest lasting bearing Bones makes, this is it. They suit dedicated street and park skaters, longboarders and anyone who puts serious kilometres on their wheels.

They're made in Switzerland with ceramic balls that are lighter, harder, stronger, waterproof and longer lasting than the finest steel balls. That means quicker acceleration, a faster and longer roll, better resistance to dirt and moisture, and balls that help repair damage to the races caused by grit. A single non-contact removable rubber shield makes cleaning easy, a high speed nylon retainer holds the balls, and the set comes with 4 bearing spacers.

About Bones

Bones Bearings comes from George Powell, the engineer who co-founded Powell Peralta in 1978. In the early 1980s he went looking for a faster, tougher skateboard bearing and worked with a small Swiss manufacturer to build one for skating rather than for machinery. That bearing became Bones Swiss, and the thinking behind it became the Bones Skate Rated standard.

Today Bones Bearings is part of the Skate One family in Santa Barbara, California, alongside Powell Peralta and Bones Wheels. The range runs from everyday Reds through Super Reds, Big Balls and Race Reds up to ceramic and Swiss-made bearings, all built to Skate Rated clearances, tolerances, materials and lubricant. Riders choose Bones because they roll well, last, and are easy to clean and service.

FAQs

Do these fit all skateboard wheels?
Yes. They're standard 608 size skateboard bearings with an 8mm bore, so they fit almost every skateboard, cruiser and longboard wheel on a standard 8mm axle. Each wheel takes two bearings, so this set of 8 does all four wheels on one board.

What does Swiss mean on Bones bearings?
It means they're actually made in Switzerland, to Bones Skate Rated specs. Bones Swiss bearings have been a skateboard benchmark since 1981. It is not an ABEC number; Bones doesn't use ABEC because that industrial rating ignores skateboard impacts and side loads.

Why ceramic?
Ceramic balls are lighter, harder and stronger than steel, and they won't rust. They accelerate quicker, roll further and help polish out dirt damage to the races, so the bearings stay fast for longer.

How do I look after Swiss Ceramics?
Flick the removable rubber shield off with a pin, soak the bearings in citrus degreaser or isopropyl alcohol, then dry them completely. Add two or three drops of skate bearing lube, refit the shields and spin them in. Keep them out of puddles and wet grass, and clean them when they sound gritty or start to slow down. The ceramic balls won't rust, but the steel races still can, so dry them properly.

Do I need spacers?
The set includes 4 spacers, one per wheel. Spacers sit on the axle between the two bearings in each wheel, so the bearings stay lined up when you tighten the axle nut. Lots of street skaters ride without them, but they help bearings spin freely and stop them being crushed if the nut is over-tightened.
