Renishaw A-5003-0060 Cmm Ball Stylus 4mm M3 Ruby Carbide

Product Description

The RENISHAW A-5003-0060 is a CMM ball stylus designed for use with coordinate measuring machines in dimensional inspection and quality control applications. It features a 4 mm ruby ball tip mounted on a solid carbide stem, threaded M3 for secure attachment to CMM probe heads and extension modules. The ruby ball provides consistent contact repeatability and resistance to wear, making it well suited for high-cycle measurement routines. Overall length is 40 mm, with an effective working length of 36 mm and a stem diameter of 2 mm. This stylus is used by metrologists, quality technicians, and precision measurement professionals in manufacturing and inspection environments.

This stylus fits standard M3-threaded CMM probe configurations and is appropriate for both contact scanning and touch-trigger measurement cycles. It is commonly used in production metrology on CMM systems where a small-diameter ball stylus is required to reach internal features, bores, or tight geometries. The 4 mm ball diameter and 40 mm length make it a practical choice for general-purpose dimensional inspection on machined parts, castings, and fabricated components in industrial and aerospace quality environments.

Key Features

• 4 mm ruby ball tip for wear resistance and consistent contact repeatability
• Solid carbide stem for high rigidity and minimal deflection during measurement
• M3 thread for compatibility with standard CMM probe heads and extension hardware
• 36 mm effective working length for access to recessed or internal features
• 40 mm overall length suits a wide range of general-purpose inspection setups
• 2 mm stem diameter balances reach with structural stiffness

Compatibility

Designed as an OEM-style replacement or standard-service stylus for M3-threaded CMM probe systems requiring a 4 mm ball diameter configuration.

Installation Notes

This stylus is installed by qualified metrologists or CMM technicians. Before changing stylus configurations, power down or pause the CMM and follow the machine manufacturer's probe change procedure to avoid collision or probe damage. Handle the ruby ball carefully during installation as impact or dropping can chip the ball and compromise measurement accuracy. After installation, perform a stylus qualification routine using the CMM software before taking production measurements.
