YG6 tungsten carbide balls in G10 grade deliver the dimensional accuracy and surface finish required for direct drop-in replacement in precision bearing seats, valve assemblies, and metering pumps — without the premature wear that shortens service intervals.\u003c\/p\u003e\n\u003cp\u003eEach ball is manufactured from YG6 grade tungsten carbide (WC with 6% cobalt binder), offering a density of approximately 14.9 g\/cm³ and a Rockwell A hardness of ≥89.5 HRA. Available diameters span 20 mm (0.787 in) through 50 mm (1.969 in), with select inch-equivalent sizes including 22.225 mm (7\/8 in), 25.4 mm (1 in), and 28.575 mm (1-1\/8 in) for compatibility with imperial-dimensioned housings. G10 grade specifies a diameter tolerance of ±0.0025 mm and a surface roughness of Ra ≤0.025 µm.\u003c\/p\u003e\n\u003cp\u003eTypical deployment scenarios include check valve seats in chemical dosing systems, ball-type flow control valves handling abrasive slurries, precision spindle bearing replacement in CNC grinding machines, and wear-resistant balls in hydraulic pump assemblies. The cobalt-bonded carbide matrix resists most dilute acids, alkalis, and organic solvents, making these balls a reliable choice for solid carbide ball bearings in corrosive process environments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e \u003cstrong\u003eCompatibility Note:\u003c\/strong\u003e These balls are dimensionally compatible with standard bearing seats and valve bodies designed for the listed diameters.

Its ≥89.5 HRA hardness translates to superior abrasion resistance in slurry and particulate-laden media. Unlike silicon nitride, YG6 also offers higher density, which aids seating in gravity check valves. The trade-off is that carbide is more brittle under impact loads compared to steel.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhich diameter should I select for my application?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eMatch the ball diameter to the seat bore diameter specified in your valve or bearing housing drawing.
