304 Stainless Steel Precision Solid Balls — available sizes: 1mm, 1.5mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm. Also listed: precision solid stainless steel ball 2.381mm (8900 grains per catty). Why choose these 304 stainless steel balls Reliable corrosion resistance and long service life from 304 stainless steel, suitable for indoor and many outdoor applications. Precision solid construction delivers consistent roundness and repeatable performance for sealing, rolling, and locating tasks. Durable and wearresistant: reduced maintenance and fewer replacements compared with plated or lowgrade alternatives. Versatile sizing: small increments from 1.0mm up to 10.0mm (plus the 2.381mm option) to match a wide range of fittings and assemblies. Key attributes Material: 304 stainless steel (austenitic stainless steel known for corrosion resistance and strength). Construction: solid, precisionmanufactured balls for uniform mass and geometry. Sizes available: 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm; also specified model 2.381 mm with marking '8900 grains per catty.' Surface: precision finish suitable for sealing surfaces, bearings, and precision assemblies. Functionality: suitable for rolling, sealing, bearing, and weight or balance applications. How this product solves common problems Eliminates leakage and uneven motion in valves and fittings by providing a precise, hard spherical sealing surface. Restores smooth rolling and reduces play in small bearings and precision mechanisms where consistent ball geometry is critical. Replaces worn or corroded balls with a corrosionresistant alternative that maintains dimensional stability in many environments. Typical applications / use cases Ball valves and check valves: worn valve balls to restore sealing performance in plumbing, pneumatic, and hydraulic assemblies. Precision mechanisms and bearings: Use in roller/bearing assemblies, sliding guides, and hobby or instrument mechanisms requiring accurate, consistent spheres. Model making, crafts, and tooling: Smalldiameter balls provide accurate weights, pivots, or decorative elements where stainless steel durability is needed. Practical notes Select the exact diameter required for fit and function; multiple sizes are available to match seat bores and bearing races. The product is supplied as precision solid 304 stainless steel balls; please verify the 2.381mm option and its listing detail (8900 grains per catty) if that specific size/notation is required for your application. For assemblies requiring magnetic properties, note that 304 stainless is generally austenitic and not strongly magnetic. What you get Precision solid stainless steel balls manufactured from 304 stainless steel in the specified diameters for reliable, repeatable performance in sealing, rolling, and precision applications. If you need a specific size or quantity, verify availability of the exact diameter before ordering to ensure fit and function for your application.
