Ball Bearing Models
National and World Champion ceramic bearings for the hardcore racer. Superlight, extremely durable, lowest friction possible, best acceleration and top speed. No-contact low resistance seals. Diamond polished Ceramic Nitride Pro Series balls which are 79% lighter than carbide and made from pure silicon nitride Si3N4. SIN lightweight synthetic lube. HSR engineered inner construction. $7.99 per ball bearing, full ball bearing kits start at $59.99.
An oldie but a goodie. For the recreational RCer. Lightweight low friction PTFE seals, and long-lasting. $2.99 per ball bearing, full ball bearing kits $29.99.
Back in 1989 in sunny Santa Monica California, we started the Ceramic Ball Bearing craze as the first company to pioneer RC Ceramic Diff Ball and Ball bearing technology. Our belief was that lightweight racing was the future of all racing and we were right. Our Ceramic Silicon Nitride Balls were harder and 79% lighter than tungsten carbide which lowered rotational mass, increased speed, decreased heat and friction, and lasted much longer.
Built for every application from aerospace to hobby, and track tested, competitive racers around the world agree: if you want to perform at a professional level, ACER Racing ceramic ball bearings are your best & only option. Our Ceramic Ball Bearings offer the freest and smoothest movement of all ball bearings. Legends in racing including Greg Degani (the first American IFMAR World Champion and ACER Racer) all trust ACER Racing's Ceramic Nitride Pro Series ceramic ball bearing, whether for cycling, skating, fishing, hobby, aerospace or in their RC vehicles. Our Ceramic ball bearings are extremely lightweight and will improve your speed, acceleration and durability all while lowering rotational mass. Additionally, ceramic ball bearings have been proven to last longer than other materials by up to 10X on average. The thermal properties of ceramic ball bearings prevent friction heat from building up, resulting in an unbeatably smooth, fast ride. Additionally, ceramic ball bearings are shatterproof and the superior properties of ceramic ball bearings prevent deformation under loads that result in consistently high-performance results over time.
ACER Racing has nearly 30 years experience in the racing industry and has earned a reputation of equipping the world’s fastest bikes, skateboards, cars, motorcycles, fishing reels and RC cars with ceramic ball bearings. Our ceramic ball bearings will allow you to race faster and longer which translated into all kinds of advantages on the road. Our top of the line Ceramic Nitride Pro Series ceramic ball bearings can be purchased in a full ball bearing kit for RC applications or individually for all applications. Our Ceramic ball bearings have become the standard for competitive bearing performance. Each of our ceramic ball bearings comes with 100% Synthetic Made in USA SIN lightweight oil which ionically bonds to the bearing surfaces allowing it to cool down and increase durability. Each of our ball bearings is sealed (except where noted) on both sides with a dual no contact seal, and everything is enclosed in an HSR inner cage for high-speed durability and performance.
Race lighter, longer only with ACER Racing.
14x25.4x6mm 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 14x25.4x6mm ceramic 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.
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.
UPDATE: ACER Racer Shasa Lackner received his trophy as "Swiss Junior Champion" using ACER Racing ceramic engine bearings in his Max Power engine. Shasa won the main final by nearly 2 laps, and set a new lap record of 14.0 seconds and his ACER Racing ceramic engine bearings worked perfectly for the entire weekend.
