Convert-a-ball 2 5/16" Ball Carbon Steel — Model 02TA by Trojan

Introducing the Convert-a-ball 2 5/16" Ball in carbon steel (Model 02TA) from Trojan — a purpose-built sphere engineered for reliability in fixtures, tooling, and mechanical assemblies. With a true, round geometry and a precise 2 5/16" diameter (58.74 mm), this solid carbon-steel ball delivers consistent seating and smooth motion where accuracy matters most.

Why this 2 5/16" ball stands out

• Exact diameter, true roundness: A precisely sized sphere that ensures predictable contact points, reducing play and drift in alignment, rotation, and seating applications.
• Durable carbon steel core: Built to withstand repeat cycles in demanding workshop environments, resisting wear while maintaining dimensional stability over time.
• Versatile performance surface: Smooth, uniform contact surface supports stable ball transfer, indexing, and detent systems without introducing irregularities.
• Standardized core for custom tooling: A reliable, readily available spherical element that integrates cleanly with housings, fixtures, and retrofit projects designed for a 2 5/16" sphere.

Ideal use cases

• Precision fixtures and jigs that require a repeatable spherical contact point for alignment and controlled movement.
• Ball transfer setups and indexing mechanisms where stable seating and smooth rotation are essential.
• Detent and coupling applications that depend on a dependable seating element for consistent engagement.
• Custom tooling or retrofit projects needing a standardized 2 5/16" carbon steel ball as a core component.

Practical guidance for best results

• Inspect the ball for nicks or flats before installation; surface imperfections can impact alignment and motion precision.
• Keep the ball clean and dry to minimize surface deterioration; store in a dry environment when not in use.
• Pair with compatible housings or fixtures designed to accommodate a 2 5/16" sphere for optimal seating and performance.

Designed for engineers and machinists who value consistency, longevity, and compatibility, the Convert-a-ball 2 5/16" Ball (02TA) is a straightforward, dependable choice for any project that demands a precise, durable spherical element. From fixtures to retrofit assemblies, this ball delivers steady performance under load, with the reliability you expect from Trojan.
