304 stainless steel solid precision balls — available sizes: 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10 mm. Also available: 7.938 mm variant (240 grains per catty). Why choose these 304 stainless steel precision balls Corrosionresistant and durable: 304 stainless steel offers reliable resistance to rust and many common corrosive environments, extending service life compared with non‑stainless alternatives. Precise, repeatable geometry: sold as precision solid balls, they provide consistent roundness and diameter for reliable mechanical fit and smooth motion where tight tolerances are required. Versatile and compatible: available in a broad range of small diameters to suit bearings, valves, instruments, fittings and hobby applications. Solid construction: each ball is solid stainless steel for predictable weight, strength, and wear performance. Key attributes Material: 304 stainless steel (solid). Available diameters: 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm. Special variant listed: 7.938 mm — 240 grains per catty (as specified). Functionality: precision spherical geometry for rolling, sealing, positioning, or decorative purposes. Performance: corrosion resistance, dimensional consistency, and long service life under normal use conditions. Typical applications Bearings and small rotating assemblies: ideal for miniature ball bearings, pivots, and rollers where precision and smooth motion are needed. Valves and flowcontrol components: used as sealing or checkvalve elements in fluid systems that benefit from stainless corrosion resistance. Precision instruments, hobby and model work: suitable for metrology components, model mechanisms, jewelry making, or detailed DIY projects that require accurate small spheres. Practical notes Select the exact diameter needed to match your housing, seat or bearing tolerance; sizes are offered across a fine range for precise fits. The 7.938 mm variant and the notation '240 grains per catty' are provided per product specification. For applications involving extreme hardness, temperature exposure beyond typical ranges, or aggressive chemicals, verify compatibility with 304 stainless steel. What you get Solid, precision 304 stainless steel balls in the selected diameter for dependable dimensional stability, corrosion resistance and versatile use across industrial, hobby and maintenance applications.
