Tungsten carbide precision balls- G5/G10/G25 grade Mainly applied for oil sealing, bearing ball, metering and milling industry.
Semi-finished carbide ball without band round ground ball. mainly used for milling industry, shots
Tungsten carbide ball blanks : It is sintered ball( unground )mainly used for milling industry.
Application :
Extremely good wear resistance and dimensional stability make tungsten carbide balls the preferred choice for grinding/milling media, precision hydraulic valves, high-load bearings, ball screws, linear bearings in slideways, gauging and checking instruments, and meters.
