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.
