12x21mm Ceramic Engine Bearing
Welcome to ACER Racing's new line of Ceramic Ball Bearings made for competition use in high performance RC car engines. These are from our Ceramic Nitride Pro Series line of world champion bearings.
These 12x21x5mm ceramic engine ball bearings feature our diamond polished Silicon Nitride ceramic balls plus a super high speed PEEK inner cage to withstand the heat and stress of your engine. Proprietary internal tolerances have been incorporated into this ceramic bearing as well.
New generation PEEK polymer was chosen for the cages because of its superior combination of strength and flexibility, high operating temperatures, and high chemical and wear resistance. The design of the cage and material used are of paramount importance for the performance of the cage as well as for the operational reliability of the bearing itself.
Ball Bearing cages are mechanically stressed by friction, strain and inertia. They may also be subjected to the chemical action of certain lubricants, lubricant additives or products of their ageing or organic solvents. The relative importance of these considerations can be affected by other operational parameters such as elevated temperatures, shock loads, vibrations or combinations of these and other conditions. The materials from which the bearing components are made determine to a large extent the performance and reliability of the rolling bearings. This why ACER Racing has used PEEK cages for our ceramic engine bearings.
PEEK cages have an excellent combination of strength and elasticity. The good sliding properties of the polymer on lubricated steel surfaces and the smoothness of the cage surfaces in contact with the rolling elements produce the lowest amount of friction so that heat generation and wear in the bearing are at a minimum. The low density of the material means that the inertia of the cage is small contributing to greater speed. The excellent running properties of polymer cages under lubricant starvation conditions permit continued operation of the bearing for some time without risk of seizure and secondary damage.
Our PEEK bearing cages show no signs of aging by temperature and oil additives up to +200 °C (392°F).
Price is for one ball bearing.
NOTE: For 12x21mm ball bearings that will NOT be used in RC car engines, please use ACER Racing part C020.
Lube so good, it should be a SIN (and it is!). The best synthetic lube for your ball bearings. Made in USA, ACER Racing's SIN lube is a 100% synthetic lightweight oil engineered to ionically bond to ball bearing surfaces and micro polishes bearing elements for a smoother, quieter, and faster bearing. Made specifically for bearing use but our customers have reported amazing results when used in numerous other applications such as a fishing reel oil, bicycle chain oil and as a general high performance lubricant. Not for use in RC differential balls. For differential balls we recommend using your kit's OEM diff ball lube. Comes in a convenient 1 ounce (28.35 gram) squeeze bottle
RPM Bearing Blaster | RPM 81170 Bearing Blaster
The perfect way to clean our ball bearings without removing our seals. Very easy to use, the RPM 81170 Bearing Blaster is the industry standard miniature ball bearing cleaning device. Use for bearings with a minimum inner diameter of 1/8" (3mm) and a maximum outer diameter of 3/4" (19mm). For larger bearings use the RPM Mega Bearing blaster by clicking HERE.
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.
These are the best ceramic skate bearings at any price. Whether used in your skateboard, inline skates, longboard, roller skates, fidget spinners or anywhere a size 608 8x22x7mm ball bearing is used, rest assured you will be running the finest ball bearings in the industry. These have become the #1 bearing for use in fidget spinners and will spin longer, smoother and faster than any other fidget spinner bearing.
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!

5X10MM Ceramic Ball Bearing for Clutch Use | MR105 Ball 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.
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.
10X15MM Ceramic Ball Bearing | 6700 Bearing
10x15mm CERAMIC BALL BEARING size 10x15x4mm or also known as size 6700 ball bearing. Made from our World Champion Ceramic Nitride Pro Series Bearing Material. Lubed with our famous SIN lightweight synthetic oil and sealed on both sides to protect against contamination. These can be used anywhere a 10x15x4mm ball bearing is required. Traxxas racers this is a direct high performance replacement for the Traxxas 5119 bearing
Size 6700 ball bearing Equivalent to Tamiya size 1510 bearing, Traxxas 5119 bearing, Team Associated 1731 bearing
Team Associated racers, this is a direct replacement for Associated 1731 which is a front one way bearing. You can use these as a performance upgrade to the AE 1731 just reuse the sleeve that comes on the factory team one way bearing. (Associated incorrectly has the 1731 bearings listed as a 3/8x5/16 bearing there is no such thing.
