Renishaw A-5003-4793 Cmm Ball Stylus Probe 3mm Ruby

Product Description

The RENISHAW A-5003-4793 is a CMM ball stylus probe designed for coordinate measuring machine applications. It features a 3 mm ruby ball tip mounted on a solid carbide stem, with a 20 mm overall length. Ruby is the standard material for CMM styli because of its hardness, dimensional stability, and low wear rate against most workpiece surfaces. This stylus is used by metrologists, quality control technicians, and precision machining professionals who require accurate, repeatable surface contact during dimensional inspection routines.

This stylus is suited for standard CMM inspection work in manufacturing, tooling, and quality assurance environments. The 20 mm overall length and 3 mm ball diameter make it appropriate for general-purpose probing of machined parts, fixtures, and molds where moderate reach and fine contact geometry are required. It is a direct-mount stylus intended for use with compatible CMM probe heads in both automated scanning and touch-trigger measurement cycles.

Key Features

• 3 mm ruby ball tip for precise, low-wear surface contact
• Solid carbide stem provides rigidity and minimizes deflection during probing
• 20 mm overall length suited for general-purpose CMM measurement tasks
• Ruby ball material offers high hardness and dimensional consistency across repeated cycles
• Compact form factor compatible with standard CMM stylus mounting interfaces

Compatibility

Designed as an OEM-style replacement or standard-supply stylus for CMM probe heads that accept M2 or equivalent threaded ball styli; verify thread specification and probe head interface requirements before installation.

Installation Notes

Installation should be performed by a qualified metrologist or CMM technician familiar with stylus change procedures for the specific probe head in use. Power down or place the CMM in a safe, parked state before changing styli to avoid probe crashes. Use the appropriate stylus-change tool or wrench as specified by the probe head manufacturer - do not overtighten, as carbide stems and ruby balls are brittle and can fracture under excess torque. After installation, perform a full stylus qualification routine to recalibrate ball center position before resuming measurement.
