Spi 14-823-9 Chrome Steel Gage Ball 13mm Grade 25

Product Description

The SPI 14-823-9 is a chrome steel gage ball designed for precision measurement applications. Manufactured to Grade 25 accuracy and certified to AFBMA standards, this hardened steel ball delivers the dimensional consistency required for gauging, inspection, and calibration tasks. The ball measures 13 mm in diameter and is supplied in a package quantity of two. Its hardened chrome steel construction resists wear and deformation under repeated contact, making it a reliable reference component in quality control environments. Metrology technicians, tool-and-die shops, and calibration labs are the primary users of this type of precision gage ball.

This gage ball is suited for use in dimensional inspection setups, go/no-go gauging fixtures, and precision measurement instruments. It is appropriate for both production floor inspection stations and laboratory calibration benches. The Grade 25 accuracy rating makes it suitable for high-tolerance measurement work where spherical form error must be tightly controlled. The package includes two balls, which is useful for setups requiring matched or redundant reference components.

Key Features

• 13 mm diameter chrome steel construction for precise dimensional reference
• Grade 25 accuracy rating for high-tolerance inspection work
• Hardened heat treatment for wear resistance and long service life
• AFBMA certified to recognized industry standards
• Supplied in a package of two balls

Compatibility

Designed as a standard precision gage ball for use in dimensional inspection fixtures, gauging instruments, and calibration equipment that accept a 13 mm diameter spherical reference component.

Installation Notes

Gage balls are handled and installed by metrology technicians and quality control personnel. Keep contact surfaces clean and free of contaminants before use, as debris can affect measurement accuracy. Use appropriate handling tools or clean cotton gloves to avoid surface contamination from skin oils. Store in a protective case when not in use to prevent nicking or surface damage that could compromise Grade 25 accuracy.
