The Right to Bear Speed

Skate bearings are cylinder shaped metal devices that allow a wheel to roll faster and smoother by reducing friction. Unlike the wheels in which they fit into, all bearings have the same dimensions- 8mm (inner diameter), 22mm (outer diameter), and 7mm (width). Each wheel requires two bearings that are usually separated within the wheel by a spacer. Bearings are measured by an ABEC rating system (1, 3, 5, 7, and 9).

Tip: You get what you pay for in bearings, the more expensive bearings will last longer and go faster. Like Ricky Bobby once said standing at the top of a hill with a Magneto board, “I wanna go fast!”.


The ABEC scale for bearings is not just used in the skate industry, it actually measures the tolerance and precision that any bearing has. ABEC 9’s, the best rating, means high precision and low tolerance, which is perfect for products that spin at fast revolutions per minute (rpm). In the skate industry a rating of ABEC 9 is seen as the best bearings for going as fast as possible.

Tip: The ABEC scale does not factor in the quality of materials used to make the bearings, make sure you check out the material comparison below.

MATERIALS (Steel VS Ceramic)

Skate bearings are typically steel or ceramic. Both have their advantages (cost vs. quality) because steel is cheaper than ceramic, but ceramic is known to be higher quality and less maintenance. Ceramic bearings will have ceramic balls on the inside of the bearing which are known to be faster than steel bearings which have… you guessed it steel balls. At the end of the day, ceramic bearings, besides the balls, will be made of steel, however, the steel used is usually higher quality in ceramic bearings. In summary, ceramic bearings cost more not only because the balls are ceramic, but the overall quality is better. An additional benefit of ceramic bearings is its inability to rust.

Tip: Ceramic bearings are the best investment for everyday and/or high impact skaters, but steel bearings (especially ABEC 9) are great until wanting to take on the investment.


Skate bearing spacers are designed to reduce the weight distribution of each bearing by providing extra support between the two bearings. This leads to smoother, more stable turns and longer bearings life. A spacer is just a metal cylinder between your bearings, 8-10mm diameter, which makes it a cheap, but positive investment.

Tip: If you can hear your spacers rattling, you need a bigger size to get the benefits.


Washers are used on the outside of each wheel to separate the bearings from additional nut and truck friction. This ultimately makes your wheels faster, while also protecting the face of the bearing.

Tip: Washers are the subjectively the cheapest part with the highest reward.


After about a year of looking for high-quality affordable aftermarket bearings, we finally gave up and just developed our own! These bearings will compete against the best bearings on the market at a fraction of the price.
