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.

12x21mm Ceramic Engine Bearing
If you need 7x17mm ceramic engine bearings please click HERE
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.

This is a 10 piece Titanium Lug Bolt Set for the Porsche 911 (1999 and newer). Manufactured from aerospace grade 6AL4V Titanium and 5mm longer than stock 29mm bolts for those of you who are using spacers on your original wheels. These titanium lug bolts will not corrode or rust and offer a significant weight savings on your Porsche while giving a very sporty and aggressive look. Rolled threads for superior fatigue resistance. Available in natural 6AL4V Titanium color or BLACK PVD titanium. M14x1.5x34
34mm shaft length measured from under the ball seat. Torx head version uses a Torx 80 bit (not included) but available in any hardware store.
If you need locking bolts please click HERE
Note: GT3, Cayenne & Taycan use a 34mm shaft which is already 5mm longer than the standard 29mm 911 shaft so please adjust accordingly. For example if you are adding 10mm spacers to your Cayenne you would need 44mm lug bolts (34mm+10mm) so you would need our lug bolts for 15mm spacers not the ones for 10mm spacers.
BLACK TITANIUM:
We do offer black titanium lug bolts for Porsche. We use a Physical Vapor Deposition (PVD) process which is much better and more durable than simply anodizing titanium. PVD is a complex process which vaporizes a number of metals and then binds them on the surface in layers in a heated vacuum. This is the same process used on the beautiful black finish of high end black luxury watches such as Rolex and Panerai watches. We are always asked if the natural titanium finish will look good against a darker wheel and our answer is yes. Natural titanium pops very nicely against a dark wheel and you will be showing off the beautiful titanium you paid for so it would make sense to go natural but many customers still prefer a black titanium so we offer the best solution with the PVD Black Titanium finish.
