Renishaw A-5003-4797 Cmm Ball Stylus 2mm M4 Ruby

Product Description

The RENISHAW A-5003-4797 is a CMM ball stylus designed for use with coordinate measuring machines in precision metrology applications. It features a 2 mm ruby ball tip mounted on a solid carbide stem with a total overall length of 50 mm and an M4 threaded shank for direct attachment to CMM probe heads and extension modules. Ruby is a preferred ball material for CMM styli due to its hardness, low friction, and dimensional stability under repeated contact cycles. This stylus is installed and qualified by metrologists, quality technicians, and CMM programmers operating in manufacturing inspection environments.

This stylus suits a wide range of CMM inspection tasks including feature measurement, bore gauging, and surface scanning on precision components. The 50 mm overall length provides reach into moderately deep features without requiring additional extensions. The M4 thread is a standard CMM interface compatible with common probe head and stylus module systems used in dimensional inspection labs and production-floor CMM cells.

Key Features

• 2 mm ruby ball tip for high-wear resistance and consistent contact point geometry
• Solid carbide stem for rigidity and minimal deflection during probing cycles
• 50 mm overall length suits moderate-depth feature access
• M4 threaded shank for direct mounting to compatible CMM probe heads and modules
• Ruby material provides low friction and long service life in repetitive contact applications

Compatibility

Designed as a direct-fit stylus for CMM systems accepting M4-threaded styli, consistent with standard probe head and stylus module interfaces used in coordinate measuring machine applications.

Installation Notes

CMM styli should be installed and qualified by trained metrologists or CMM technicians following the machine manufacturer's qualification procedure. The probe head and any active scanning module must be in a safe, parked position before stylus exchange. Use the manufacturer-recommended torque tool or finger-tighten only per machine guidelines to avoid thread damage or seating error. After installation, always run a full stylus qualification routine before taking measurements to establish accurate ball center compensation.
