Product Description

G25 Tungsten Carbide Machinery Bearing Balls For Radio 4.76MM 9.525MM 3.56MM
 

Tungsten carbide balls provide a binder percentage slightly higher than the standard balls (7-9%).
 
They are available on demand.
 
The mechanical properties and corrosion resistance are a little lower if compared to standard K20 balls.
 
Virgin powder is strictly used into this kind of production.
 
 
Applications
Special and hydraulic precision valves, special bearings, couplers, flow meters, sprayers, recirculating balls, ball spindles, tooling machines, sliding rails, ballpoint pens, pin and tips for indicators, precision measurement instruments, medical instruments. They are used in naval, mining, petrol and coining industry.
