Steel Ball

Overview

Steel Ball product family comprising three form-factors: SBS (Steel Ball Sphere), SBF (Steel Ball Flying Saucer) and SBN (Double-ended needle). Material: low carbon steel wire. Surface hardness: HRC 55mins. Primary function: metallic glossy finish when used combined with abrasive compounds. Available SBS sphere sizes (inch = mm): 1/4 = 6.350; 7/32 = 5.556; 3/16 = 4.762; 5/32 = 3.969; 1/8 = 3.175; 3/32 = 2.381; 1/16 = 1.588. SBS item numbers listed: - 6; - 5; - 4; - 3; - 2; - 1. SBF flying-saucer specifications (inch = mm) with outer diameters: 1) 1/4 = 6.350 (outer diameter: 8.43); 2) 3/16 = 4.762 (outer diameter: 6.54); 3) 5/32 = 3.969 (outer diameter: 5.94); 4) 1/8 = 3.175 (outer diameter: 4.38). SBF item numbers listed: - 6; - 5; - 4; - 3. SBN double-ended needle: SBN item No. 2; specification entry given as "2×10" (inch(inch)=mm). All SKUs are described for fine polishing — Glossy Finish. Designed for industrial polishing/finishing workflows where a metallic glossy surface is required by combining these steel media with abrasive compounds. The product line covers a range of contact geometries and sizes so users can match media shape and diameter to part geometry and desired surface profile. In practice, choose SBS sphere sizes for general fine polishing of small to mid-sized components, SBF flying-saucer shapes where a larger effective contact or edge interaction is beneficial (outer diameters provided), and the SBN double-ended needle configuration where the needle form-factor and its listed specification are needed. The HRC 55mins surface hardness indicates suitability for repeated finishing cycles in production-scale finishing operations and manufacturing R&D environments.
