Renishaw A-5000-4155 Cmm Ball Stylus 5mm Ruby M2

Product Description

The RENISHAW A-5000-4155 is a CMM ball stylus designed for use with coordinate measuring machines in dimensional inspection and quality control applications. It features a 5 mm ruby ball mounted on a stainless steel stem with an M2 threaded connection. The overall length is 10 mm, with an effective working length of 10 mm and a stem diameter of 2.5 mm. The ruby ball provides excellent hardness and wear resistance, making it well suited for high-cycle probing routines where consistent contact accuracy is required. Metrology technicians and quality engineers install this stylus as part of a CMM probing system.

This stylus is used in dimensional metrology environments including manufacturing inspection cells, quality labs, and production floor CMM stations. It is appropriate for measuring tight-tolerance features on machined parts, castings, and assemblies where a small-diameter ruby ball and compact overall length are needed to access confined geometry. The M2 thread interfaces with compatible stylus holders, extensions, and probe modules in standard CMM configurations.

Key Features

• 5 mm ruby ball for high wear resistance and consistent probing accuracy
• 10 mm overall length suited for access to shallow or confined features
• M2 threaded connection for compatibility with standard CMM stylus systems
• 2.5 mm stainless steel stem balances rigidity with low deflection
• Compact form factor supports use on multi-stylus configurations and star arrangements

Compatibility

Designed as an OEM-style replacement or standard consumable stylus for CMM probing systems that accept M2 threaded styli.

Installation Notes

Installation is performed by metrology technicians or quality engineers familiar with CMM qualification procedures. The stylus should be threaded in by hand until snug and then tightened to the probe module using the appropriate stylus wrench - avoid overtightening, which can damage the M2 thread or affect calibration. After installation, perform a full stylus qualification routine on the CMM controller before taking measurements. Ensure the machine is in a safe, stationary state and the probe head is powered down or in a protected mode before handling styli.
