Bones Super Swiss 6 bearings (SS6) are fundamentally different from their famous Bones Swiss. Super Swiss have 6, 3/16 inch balls instead of 7, 5/32 inch balls. Thus, the SS6 balls are 20% larger and roll fewer times to go the same distance. Like bigger wheels on a car, they create less rolling friction and have a higher top speed.
SS6's special design and Swiss quality materials enable it to accelerate quicker, roll faster, and resist the impact of skate trick landings better than standard designs.
Skate Rated™ - Skate Rated bearings are engineered and tested by Bones Wheels to withstand the high impacts of hard landings and the high side loads of turning. These bearings roll faster and last longer than bearings that use the ABEC rating system. To give Skate Rated bearings an ABEC rating would ignore all the improvements Bones has made over the industry standard. Skate Rated bearings are specifically designed for skateboarding, not electric motors.
Swiss - Swiss bearings accelerate faster, roll smoother and last longer than traditional steel bearings.
Made in Switzerland - All Bones Swiss bearings are made in their factory located in Switzerland.
