| Performance |
1. High strength and high toughness, no broken beads under high-speed impact. |
1.59% lighter than steel balls, which means less centrifugal force and wears less grooves at high speeds and accelerations |
Silicon carbide ceramic balls have stable performance, and silicon nitride has good overall performance. Compared with steel, its |
