Hybrid Si3N4 Ball Bearing 608 For Skateboard Or Fidget Spinner With High Speed And Low Noise
Description of Hybrid Si3N4 Ball Bearing 608:
1. GCr15 Races: GCr15 bearing steel is a kind of high carbon chromium bearing steel with less alloy content, good performance and the most widely used. After quenching and tempering, it has high and uniform hardness, good wear resistance and high contact fatigue performance. The steel has moderate cold working plasticity, general cutting performance, poor welding performance, great sensitivity to the formation of white spots, and temper brittleness.
2. Si3N4 ceramic balls: Are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is processed by HIP (Hot Isostatic Pressure) sintering technology.
3. PEEK cage and seals: The crown structure cages and seals are adopted British Victrex PEEK material.
Performance advantages of Hybrid Si3N4 Ball Bearing 608:
Because of the outstanding properties of materials the hybrid Si3N4 ball bearing 608 can operate smoothly and fastly whether with lubrication or not.
Application of Hybrid Si3N4 Ball Bearing 608:
Hybrid Si3N4 ball bearing 608 with outstanding operating performance is one of the best choice of skateboard and fidget spinner bearing.
