Renishaw A-5003-0036 Cmm Ball Stylus 2mm Ruby M2

Product Description

The RENISHAW A-5003-0036 is a CMM ball stylus designed for coordinate measuring machine applications requiring high-precision contact measurement. The stylus features a 2 mm ruby ball with a solid carbide stem and M2 thread for secure mounting to compatible CMM probe systems. Overall length is 30 mm, with an effective working length of 22.50 mm and a stem diameter of 1.50 mm. Ruby is the preferred ball material for CMM styli due to its hardness and dimensional stability under repeated contact. Licensed CMM technicians and metrology lab personnel are the primary installers and users of this component.

This stylus is suited for precision dimensional inspection in manufacturing and quality control environments. It fits standard M2-threaded CMM probe bodies and stylus extension assemblies. Typical applications include surface probing on machined parts, bore measurement, and feature location on coordinate measuring machines in both production and inspection settings. The compact 2 mm ball diameter allows access to small features and tight geometries where larger styli cannot reach.

Key Features

• 2 mm ruby ball for high hardness and consistent contact geometry
• Solid carbide stem for rigidity and minimal deflection during probing
• M2 thread for compatibility with standard CMM probe and extension systems
• 22.50 mm effective working length for reach into recessed features
• 30 mm overall length in a compact, low-mass configuration
• 1.50 mm stem diameter balances reach with structural stiffness

Compatibility

Designed as an OEM-style replacement or spare stylus for CMM probe systems accepting M2-threaded styli. Verify probe body thread type and stylus module interface before installation.

Installation Notes

CMM styli are installed and serviced by metrology technicians following the CMM manufacturer guidelines. Power down or pause the CMM and retract the probe head before changing styli to avoid damage to the probe or the part under inspection. Handle the ruby ball with care and avoid contact with hard surfaces that could chip or contaminate the ball, as surface damage will affect measurement accuracy. Clean the M2 thread and mating probe thread before assembly to ensure proper seating and torque transfer.
