6900 Ceramic Bearing also referred to as a size 61900 ball bearing Dimensions are 10x22x6mm
Our 6900 ceramic silicon nitride ball bearings are high-performance components that offer exceptional durability and efficiency in various industries, including cycling, RC models, automotive, aerospace, and precision machinery. These bearings are part of the 6900 series and feature a construction using silicon nitride ceramic material, known for its outstanding properties.
The size 6900 designation indicates the bearing's dimensions, with an inner diameter of 10 millimeters, an outer diameter of 22 millimeters, and a width of 6 millimeters. This compact size makes them suitable for applications where space is limited, while still providing robust performance.
Ceramic silicon nitride ball bearings provide several advantages over traditional steel bearings. Silicon nitride ceramic material offers superior hardness, reduced friction, excellent wear resistance, and resistance to corrosion and high temperatures.
One of the primary benefits of 6900 ceramic silicon nitride ball bearings is their reduced friction coefficient. Ceramic balls have a smoother surface and lower density than steel balls, resulting in reduced friction during rotation. This leads to improved efficiency, lower energy consumption, and reduced heat generation, making them ideal for high-speed applications.
Furthermore, the silicon nitride ceramic material used in these bearings provides exceptional hardness and wear resistance. This allows the bearings to withstand heavy loads, impacts, and abrasive conditions without premature wear or damage. The increased durability of ceramic silicon nitride ball bearings translates into extended service life, reduced maintenance requirements, and cost savings for industries.
Ceramic silicon nitride ball bearings also exhibit excellent corrosion resistance. They can withstand exposure to moisture, chemicals, and harsh environments without compromising their performance or structural integrity. This corrosion resistance ensures reliable operation in challenging conditions and contributes to the longevity of the bearings.
ACER Racing's size 6900 ceramic silicon nitride ball bearings offer exceptional performance and durability due to their silicon nitride ceramic construction. These bearings provide reduced friction, improved efficiency, enhanced wear resistance, and corrosion resistance. Whether used in automotive, aerospace, or precision machinery applications, 6900 ceramic silicon nitride ball bearings continue to deliver reliable and efficient performance in demanding operating conditions.

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 a special synthetic 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 bearing is laser etched with our trademark "CERAMIC NITRIDE PRO SERIES" logo to insure that you are receiving the original ACER SK8 ceramic skate ball bearings.

Specifically they will fit Campagnolo rear hubs and bottom brackets, Shimano rear hubs and bottom brackets, Shimano headsets models M735-M736-M650-M651. The majority of rear hubs will require nine of our 1/4" silicon nitride balls on each side and bottom brackets will use eleven of our 1/4" silicon nitride balls.
Our 1/4" silicon nitride balls for bicycles have gained significant recognition in the cycling industry due to their exceptional performance and durability. These balls, made from advanced silicon nitride ceramic material, offer unique advantages over traditional steel balls, making them a preferred choice for high-performance bicycle applications and anywhere a strong, hard and lightweight ball is required.
The 1/4" size designation refers to the diameter of the silicon nitride balls, which measures approximately 6.35 millimeters. This size is specifically tailored to meet the requirements of bicycle components such as hubs, bottom brackets, and headset bearings.
One of the key benefits of using 1/4" silicon nitride ceramic balls in bicycles is their reduced weight compared to steel balls. The lightweight nature of the silicon nitride material helps to reduce the overall weight of the bicycle, contributing to improved speed, maneuverability, and responsiveness. This weight reduction is particularly advantageous in competitive cycling, where every gram matters.
Moreover, the silicon nitride balls offer exceptional hardness and superior wear resistance. This ensures prolonged service life and reduced maintenance requirements, making them an excellent choice for demanding cycling conditions. The durability of these balls allows cyclists to ride with confidence, knowing that their components can withstand the rigors of off-road trails, rough terrains, and high-speed descents.
Additionally, the silicon nitride material exhibits excellent corrosion resistance. This is particularly beneficial for cyclists who ride in wet or humid environments, as the balls can withstand exposure to moisture without compromising their performance. The corrosion resistance ensures smooth rotation, reduces the risk of rust formation, and extends the lifespan of the bicycle components.
Furthermore, our silicon nitride balls have a very low coefficient of friction, resulting in reduced energy loss and improved efficiency. This translates to enhanced power transfer, allowing cyclists to pedal more efficiently and effectively. The reduced friction also contributes to smoother operation, reduced wear on surrounding components, and a more enjoyable riding experience.
ACER Racing's 1/4" silicon nitride balls for bicycles offer exceptional performance, durability, and weight reduction advantages. Their advanced ceramic construction, reduced weight, wear resistance, corrosion resistance, and low friction make them a preferred choice for cyclists looking to enhance their performance and reliability. Whether used in road bikes, mountain bikes, or other cycling disciplines, these balls continue to prove their worth by delivering optimal performance and reliability on the road or trail.
