The development of new ceramic materials makes ceramic bearings more accessible!
We would like to introduce our "New Ceramic Ball Bearings for Motors." The coefficient of linear expansion is close to that of the inner and outer ring materials (bearing steel SUJ2), resulting in minimal changes in the internal clearance of the bearing due to temperature variations, making it suitable for a wide range of temperature environments. It possesses similar insulation properties, strength, and durability (changes in acoustic values) as conventional insulating materials such as silicon nitride (conventional ceramics Si3N4). 【Material Properties (Partial)】 ■ Density (g/cm3): 6 ■ Coefficient of Linear Expansion (1/℃): 10.5×10^−6 ■ Vickers Hardness (HV): 1280 ■ Longitudinal Elastic Modulus (GPa): 210 ■ Poisson's Ratio: 0.31 *For more details, please refer to the PDF document or feel free to contact us.
