Carbide sphere application:

1. Critical bearings: Used in precision machinery operating at high speeds, under heavy loads, or in corrosive environments, such as advanced CNC machine tools and aerospace equipment.

2. Oil valves: Used in pumps used in oil drilling, they withstand immense pressure and abrasion from sand and gravel.

3. Chemical pumps and valves: Pumps and valves used to transport abrasive slurries or chemical liquids, and are much more durable than steel balls.

4. Pen tip beads: The small ball in the tip of a high-end ballpoint pen ensures smooth writing even after hundreds of thousands of words.

5. Precision measurement: Used as probes in precision measuring instruments, they are resistant to wear and maintain accuracy over time.
