Renishaw A-5003-0037 Cmm Ball Stylus 2mm Ruby M2

Product Description

The RENISHAW A-5003-0037 is a CMM ball stylus designed for use with coordinate measuring machines in dimensional inspection and metrology applications. It features a 2 mm ruby ball tip mounted on a solid carbide stem with an M2 thread connection. The overall length is 40 mm (1.5748 inches), with an effective working length of 32.50 mm (1.2795 inches) and a stem diameter of 1.50 mm (0.0591 inches). Ruby is the preferred ball material for CMM styli due to its hardness and low friction against most workpiece surfaces. This stylus is installed by metrology technicians and CMM operators in quality control and manufacturing inspection environments.

This stylus is suited for residential and light industrial CMM systems that accept M2 threaded styli. It is appropriate for probing small features, tight geometries, and precision bores where a 2 mm ball diameter provides adequate access without sacrificing measurement repeatability. Typical applications include dimensional verification of machined components, tooling, and assemblies in production and inspection settings.

Key Features

• 2 mm ruby ball tip for high hardness and consistent contact performance
• Solid carbide stem provides rigidity and minimizes deflection during measurement
• M2 thread interface for compatibility with standard CMM probe systems
• 40 mm overall length with 32.50 mm effective working length for reaching recessed features
• 1.50 mm stem diameter supports access to narrow features

Compatibility

Designed as an OEM-style replacement or standard-fit stylus for CMM probe systems accepting M2 threaded ball styli.

Installation Notes

CMM ball styli should be installed and replaced by qualified metrology technicians or CMM operators. Power down or disable the CMM probe head before changing styli to prevent damage to the probe mechanism. Use the appropriate torque tool or stylus wrench as specified by the CMM manufacturer - do not overtighten, as this can damage the M2 thread or affect calibration. After installation, re-qualify the stylus using the machine's standard qualification routine before taking measurements.
