| 8 | 22 | 7 | SMR608C-2RU TH9 C3 A9 SI3N4 | ABEC-9 | Stainless steel | SI3N4 | 1. High speed nylon cage: | |
| SMR608C-2RU TH9 C3 A9 ZRO2 | ABEC-9 | ZRO2 | Using a high speed nylon cage simply because, although it does have better sliding characteristics and slightly better low noise performance, it is more forgiving if the bearing is contaminated with dirt or being used with inadequate lubrication which may be important if your bearings are overdue for cleaning and re-lubrication. | |||||

| MR608C-2RU TH9 C3 A9 ZRO2 | ABEC-9 | ZRO2 | A better solution is the non contact seal. This design gives better protection than shields but without the drag caused by normal seals. Finally, as they are only a push fit in the outer ring of the bearing, non contact seals can be easily removed and re-fitted when you clean and re-lubricate the bearing. | |||||

| MR608C-2RU TH9 C3 A3 SI3N4 | ABEC-3 | SI3N4 | The internal clearance of the bearing relates to the space between the balls and the raceways. A bearing is designed to take mainly radial load (vertical load on skate bearings) and some axial (side) load. The clearance on our skate bearings is slightly larger than standard and designed to allow the bearings to take a greater side load when needed. | |||||

| MR608C-2RU TH9 C3 A3 SI3N4 BLACK | ABEC-3 | SI3N4 | Skate bearings contain is a high speed, low torque grease manufactured by Klueber who make lubricants for some of the most demanding applications in industry and aerospace. It contains hard wearing lithium which is more than tough enough for skate conditions. The amount of grease in our skate bearings is carefully chosen to provide excellent lubrication but minimal drag. | |||||

Inside the wheels are the bearings which are the little metal donuts. They are rated by what is called an ABEC rating from 1 to 9 which are almost meaningless for skateboarding. That is because the rating is for the precision of a bearing for how they would work in a machine not a skateboard. An ABEC rating of 3 to 5 usually works for skateboarding because that means they are not so precise that they will break easily, but smooth enough so they are good for riding.
much lighter, harder, stronger, waterproof, and longer lasting; accelerate faster, roll faster and farther, resist dirt and moisture better | ||||||||
