5Pcs 3/8″(9.525mm) Ceramic Bearing Balls, Al2O3 Ceramic Balls G10 Precision
Description:Material: These ceramic bearing balls are made of alumina, exhibiting high stability in corrosive environments such as acids and salt spray. They are also heat-resistant, maintaining performance for extended periods at high temperatures, making them suitable for harsh environments.Low Friction: The bearing balls polished surface is smooth and crack-free, resulting in a low coefficient of friction and good rotational flexibility. They can operate under oil-free lubrication conditions and possess electrical insulation and non-magnetic properties, effectively avoiding electromagnetic interference and corrosion problems.
