Renishaw A-5003-0058 Cmm Ball Stylus 3mm Ruby M3

Product Description

The RENISHAW A-5003-0058 is a CMM ball stylus designed for coordinate measuring machine applications requiring precise, repeatable contact measurement. It features a 3 mm ruby ball tip mounted on a solid carbide stem, threaded M3 for direct installation into CMM probe heads and extension modules. The ruby point delivers consistent hardness and wear resistance across high-cycle scanning and touch-trigger operations. Overall length is 40 mm, with an effective working length of 33.70 mm and a stem diameter of 2 mm. This stylus is used by metrology technicians and quality control professionals in manufacturing and inspection environments.

This stylus suits residential and commercial precision measurement setups where repeatable surface contact is critical. It is appropriate for use in touch-trigger and scanning CMM probe configurations. The M3 thread is a standard interface across a wide range of CMM probe bodies, extension bars, and styli changers. It is commonly deployed in quality assurance labs, production floor inspection cells, and tool-and-die measurement applications where small-diameter, high-accuracy styli are required.

Key Features

• 3 mm ruby ball tip for consistent hardness and wear resistance across high-cycle use
• Solid carbide stem provides rigidity and minimizes deflection during measurement
• M3 thread interface compatible with standard CMM probe bodies and extension modules
• 40 mm overall length with 33.70 mm effective working length for reach into tight features
• 2 mm stem diameter balances rigidity with clearance in confined measurement zones

Compatibility

Designed as an OEM-style replacement or direct-fit stylus for CMM probe systems using the M3 thread standard.

Installation Notes

Installation is performed by metrology technicians familiar with CMM probe systems and stylus qualification procedures. Power down or disable the CMM measurement program before changing styli to avoid probe damage. Thread the stylus into the probe body or extension module by hand until snug, taking care not to overtighten, as ruby ball styli are susceptible to damage from excessive torque. After installation, re-qualify the stylus using the CMM qualification routine before taking measurements.
