Renishaw A-5003-0040 Cmm Ball Stylus 3mm Ruby M2

Product Description

The RENISHAW A-5003-0040 is a CMM ball stylus designed for use with coordinate measuring machines in dimensional inspection and quality control applications. It features a 3 mm ruby ball tip mounted on a solid carbide stem with an M2 thread interface. The ruby point provides excellent hardness and wear resistance, supporting repeatable contact measurements over extended service life. Overall length is 30 mm, with an effective working length of 27 mm and a stem diameter of 2 mm. This stylus is installed and swapped by metrologists, quality technicians, and CMM operators working in precision manufacturing environments.

The A-5003-0040 is suited for touch-trigger and scanning CMM probing applications in residential production, tool and die, aerospace, and general precision machining shops. It is a direct-fit M2-threaded stylus compatible with M2 probe head ports. The compact 30 mm overall length makes it appropriate for measuring features in tight or recessed geometries where longer styli would introduce excessive bending error. No specific OEM-compatible model numbers were provided in the product data.

Key Features

• Ruby ball tip at 3 mm diameter for high wear resistance and dimensional consistency
• Solid carbide stem minimizes deflection and maximizes measurement repeatability
• M2 thread interface for broad compatibility with standard CMM probe heads
• 27 mm effective working length suits shallow-to-moderate depth feature access
• 30 mm overall length supports space-constrained inspection setups

Compatibility

Designed as an OEM-style replacement or standard-fit stylus for CMM probe heads with M2 thread ports. No specific compatible model numbers or system families were identified in the product data.

Installation Notes

CMM styli are installed and removed by qualified metrology technicians or CMM operators. Power down or pause the CMM and retract the probe head to a safe position before changing styli. Use a stylus wrench or the manufacturer-recommended tool to seat the M2 thread without overtightening, which can damage the thread or alter the stylus qualification offset. After installation, re-qualify the stylus on the reference sphere before resuming measurement routines.
