Specification AgeRangeDescription : adult Brand : FOCMKEAS BulletPoint : ball bearing BulletPoint1 : 【Size】 Diameter 1/8"(3.175mm), G5 precision grade(tolerance 5/1000000),Package includes 25 pieces balls. BulletPoint2 : 【Material】Made by Silicon Nitride Si3N4 is a material with high hardness(up to 1700HV), very high resistance to high-temp(up to 2200℉) and resist most of chemicals. BulletPoint3 : 【Smooth surface】 Fine grinding to ensure that each ceramic ball is uniform in size. The surface of the ceramic ball is very smooth, easy to shape without cracks. Good self-lubricating. BulletPoint4 : 【Features】The silicon nitride balls have excellent abrasion resistance, corrosion resistance, stable, insulation and lightweight. BulletPoint5 : 【Application】Silicon Nitride ceramic balls are mainly used in aggressive environment as valve balls, wheels and bottom brackets of bicycle, full ceramic bearings, track balls, fine grinding balls, and can be used in high temperature, insulation, magnetic insulation, and non-lubrication applications.
