1"(25.4mm) Solid Precision Balls Bearing Steel / Stainless Steel / Iron / Brass

For maximum durability in high-load applications, Gcr15 bearing steel is ideal with its 62 HRC hardness. For corrosive environments, choose 440 stainless steel, which combines 58 HRC hardness with good corrosion resistance.

Yes! We offer custom material mixes - simply contact us before ordering. Popular combinations include stainless steel for structural components paired with brass balls for decorative accents in the same project.

Our 304 and 316 stainless steel balls are FDA-compliant for food contact. 316 is preferred for saltwater/sanitary applications due to its superior pitting resistance. All food-grade balls come with certification documentation.

Weight varies by density: Steel ≈ 66g, Brass ≈ 74g, Iron ≈ 68g per ball. The brass balls are noticeably heavier (12% more than steel), which can be advantageous for pendulum or inertial applications.

We provide value-added services including: laser engraving (for identification), specialty polishing (mirror/matte finishes), and precision balancing (for rotational applications). Minimum quantities apply - contact our customization team.
