SMOOTHER, LIGHTER, FASTER: these are super high end top of the line skate bearings.

8 piece ACER SK8 Size 608 Ceramic Skate Bearing 8x22x7mm. Introductory price: these are the BEST skate bearings anywhere - GUARANTEED - or your money back! ABEC 7, 100% synthetic ACER Racing SIN oil lubricant, superlite bearings. If you’re looking for the longest spinning 608 skate bearings you came to the right place.

With ACER Racing's National and World Champion reputation in the high performance ball bearing industry we set out to engineer the best ceramic skate bearing at any price.

First we started with our tried and tested Ceramic Nitride Pro Series silicon nitride balls (Si3N4). The same super hard balls that gave us the reputation as "the hardest balls in the industry." These balls are matched for consistent concentricity per set. They are polished using diamonds for a super smooth and shiny finish. Their durability is unmatched by any other ball or material in the industry. With a melting temperature of 2552 degrees F and the best modulus of elasticity in the world, these are the best balls period.

We use our special synthetic and American ACER Racing SIN oil lubrication in our ceramic skate bearings which has an extremely wide service temperature range of from -50 to +120 degrees Celsius with an incredible speed factor of 1 million.

We integrate our HSR inner ball bearing cage for durability and strength with superior heat resistance at high RPMs. This insures that your ceramic skate bearings will spin faster, longer.

We seal our ACER SK8 ceramic skate bearings with two no contact grey seals which will resist the elements while allowing simple removal for easy cleaning when necessary. Each seal is embossed with our trademark "ACER RACING CERAMIC" logo to insure that you are receiving the original ACER SK8 ceramic skate ball bearings.

UPDATE: World Champion speed skater Peter Doucet sets new lap time .3 seconds faster than before with ACER SK8 Ceramic Skate Bearings. This is very significant considering the laps are only 10 seconds each. Congratulations Peter!

(Bearing seal removed for photo only - bearings come sealed on both sides. 8x22mm bearing)

5x10mm CERAMIC BALL BEARING designed specifically to withstand the high stress and heat caused by clutchbells during competitive use. We have engineered a specific internal race tolerance within the ball bearing, used our special HSR cage for high speed reliability and injected the ball bearing with our SIN grease to help it stay cool under high stress. This is the same clutch ball bearing used by our pro racing team. The best clutch ball bearing hands down.

Price is per one ball bearing.

Size MR105 bearing
Tamiya size 1050 bearing

5x10x4mm ceramic ball bearing (4mm wide)

8x16mm CERAMIC BALL BEARING size 8x16x5mm or 688 size bearing. Made from our World Champion Ceramic Nitride Pro Series Bearing Material. Our 688 bearing is sealed on both sides with our special no contact grey seal to protect against the elements without friction producing seal contact with the bearing elements. Inside our 688 bearing is our unique HSR inner cage which is designed to withstand high RPM, high stress and heat without causing bearing fatigue. The HSR cage houses our diamond polished silicon nitride ceramic balls which have been proven race after race to be the fastest, lightest, smoothest and hardest balls in the industry. Lightly oiled, not greased, with our slippery and fully synthetic SIN oil to keep your bearing running fast and cool.

Price is for 1 bearing.

Check out this link on RCTech for more information http://www.rctech.net/forum/electric-road/49177-team-associated-tc4-594.html).

Made from our World Champion Ceramic Nitride Pro Series Bearing Material. 17x30x7mm Ceramic Ball Bearing size 6903 ball bearing. This 17x30mm bearing is a super high performance ceramic bearing which can be used for many high performance applications including bicycles (this is a direct performance upgrade for a Fulcrum R4-004 bearing) and as a direct performance upgrade and replacement for the HPI Baja.

6806 Ceramic Bearing

6806 Ceramic ball bearing with dimensions of 30x42x7mm. 30mm inner diameter, 42mm outer diameter and 7mm width. Grade 5 Silicon Nitride Ceramic balls, the hardest and strongest ceramic material available, ACERGoo Made in USA 100% synthetic lubrication, dual removable seals. These are the ultimate 6806 bearing and can also be used in BB30 bearing applications.

Cyclists with the need for speed and bike manufacturers alike have grown to trust ACER Racing for making products that bring out the best in their bicycles. Our 6806 ceramic bearing can help bike racers and enthusiasts alike obtain the highest level of performance thanks to our skillful and innovative design and because the right kind of ceramic bearing brings major benefits in terms of durability, friction and heat resistance, as well as a tremendous decrease in rotational mass meaning less pedal effort in each pedal as a result of less friction and less rolling resistance resulting in more pedal power hitting the road.

At ACER Racing, we are internationally known for making the hardest, lightest and smoothest balls in the industry and our bearings in every material are designed with performance in mind. Our super lightweight ceramic bearings are lighter and less weight, lower friction and less rotational weight means you race faster, longer.
