BCA National Taper Roller Bearings are designed to provide constrained relative motion between two rotating parts of the vehicle. These bearings are made from solid steel material which has high resistance to fatigue failure. They also enhance the efficiency and facilitate high speed.
All Bones Bearings are Skate Rated to withstand the destructive forces created by high performance skating. This is our way of saying that just using a bearing with an ABEC rating is not enough to ensure that a bearing will perform well for skating, since ABEC ratings were intended for electric motor bearings, not skate bearings. That's why they roll faster and last longer than mere ABEC rated bearings.

Single, non-contact, removable rubber shield for easy cleaning and less friction
High speed nylon ball retainer for greater strength and speed
Pre-lubricated with Speed Cream racing lubricant
Bones Bearings products have a lifetime warranty which protects them against manufacturing defects.
This unique design features six larger diameter balls instead of seven. The advantage is higher speed, quicker acceleration, greater strength and durability
Bones Super Swiss 6 bearings (SS6) are fundamentally different from our 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.
