Renishaw A-5000-3553 Cmm Ball Stylus 3mm Ruby M3

Product Description

The RENISHAW A-5000-3553 is a CMM ball stylus designed for coordinate measuring machine probing applications. It features a 3 mm ruby ball tip mounted on a stainless steel stem with an M3 thread interface. The overall length is 21 mm with an effective working length of 14.70 mm, making it suitable for standard reach probing tasks. Metrology technicians and CMM operators install this stylus when precise dimensional inspection is required. The ruby ball provides consistent hardness and wear resistance for repeatable contact measurements across production and quality control environments.

This stylus is used in CMM inspection setups across manufacturing, tooling, and quality assurance environments. It is suited for both shop-floor and lab-grade coordinate measuring machines that accept M3 threaded styli. The compact 21 mm overall length and 1.50 mm stem diameter make it appropriate for measuring features with moderate access clearance. It is commonly used by metrology technicians performing dimensional inspection on machined parts, castings, and assemblies in both low-volume and high-volume production settings.

Key Features

• Ruby ball tip for high hardness, low wear, and repeatable contact measurement
• 3 mm ball diameter for general-purpose CMM probing
• M3 thread connection for compatibility with standard CMM probe heads
• Stainless steel stem resists corrosion and provides stable stylus rigidity
• 21 mm overall length with 14.70 mm effective working length for moderate-reach access
• 1.50 mm stem diameter minimizes deflection at standard probing forces

Compatibility

Designed as an OEM-style replacement or standard-fitment stylus for CMM probe systems accepting M3 threaded ball styli.

Installation Notes

CMM styli should be installed by qualified metrology technicians or CMM operators. Power down or pause the CMM and retract the probe head before changing styli to prevent damage to the probe mechanism or the ruby ball. Thread the M3 stylus carefully by hand to avoid cross-threading, and torque only to the probe manufacturer's specified value using the appropriate tool. Requalify the stylus with the CMM's reference sphere after installation to establish accurate tip position data before measuring parts.
