Question 1

Are these abec 9? I want them for my new long board.

Accepted Answer

Hi, Thank you for your interest with Bones Reds. ABEC ratings are not relevant in any skating application. Allow me to explain. ABEC is a scale for tolerances. The higher the ABEC number, the more precise the bearing is. At the onset, this sounds relevant. However, ABEC ratings are most useful when comparing bearings in a low load and very high RPM (revolutions per minute) environment. Skateboarding, scooters, and roller skates are high load, low RPM. Because of this and the exposure to dirt, water, etc makes ABEC ratings lose their relevance as soon as your wheels hit the ground. Frankly, skate companies have used ABEC scales just to create price tiers of products. While the bearing quality might be better at a higher ABEC rating, it is wrong to assume a higher ABEC rating means a better bearing. It is much more important to look at the brand reputation, the type of lubricant used, and the bearing shield style. These features will make a huge difference. Bones Reds are the #1 selling skateboard bearing on Amazon because they are excellent. Our store promises 100% satisfaction. We hope this helps. Please feel free to contact us with any other questions or concerns. Thanks,David

Question 2

Will they work with 60mm wheels. Any size pack should I get?

Accepted Answer

Yes, these will fit 60mm wheels. If you are installing in a skateboard, they will work. If you are installing on skates, please check the axle size to make sure you need 8mm bearings.

Question 3

what are the speed rings for?

Accepted Answer

Hi Isaac, Thank you for your interest with Bones Reds. The speed rings are little washers that go on either side of the wheel to make sure the bearing does not rub on the axle nut or truck.
