Renishaw A-5003-0044 Cmm Ball Stylus 4mm Ruby M2

Product Description

The RENISHAW A-5003-0044 is a CMM ball stylus designed for use with coordinate measuring machines in precision metrology applications. It features a 4 mm ruby ball tip mounted on a solid carbide stem with an M2 threaded connection. The overall length is 40 mm, and the effective working length is 40 mm, making it suitable for standard-depth feature measurement. Ruby is the preferred ball material for CMM styli due to its hardness and dimensional stability under repeated contact. The carbide stem provides rigidity and minimizes deflection during probing cycles. This stylus is installed and calibrated by metrology technicians and quality control professionals.

This stylus is used in dimensional inspection on CMM systems in manufacturing, quality assurance, and toolroom environments. It is suited for measuring bores, surfaces, and features on machined components in both production and inspection settings. The M2 thread is a common interface on a wide range of CMM probe heads, making this a frequently specified replacement or supplemental stylus for probing configurations that require a compact, direct-mount ball stylus.

Key Features

• 4 mm ruby ball tip for hard, dimensionally stable contact measurement
• Solid carbide stem minimizes deflection and maximizes probing rigidity
• M2 threaded connection for compatibility with standard CMM probe heads
• 40 mm overall length suits standard-depth feature access
• 2 mm stem diameter provides a balance of reach and stiffness

Compatibility

Designed as an OEM-style replacement or supplemental stylus for CMM probe heads accepting M2 threaded styli.

Installation Notes

CMM styli are installed by metrology technicians following the CMM manufacturer's qualification and calibration procedures. Power down or pause the CMM and disengage the probe head before changing styli to avoid damage to the probe mechanism. Hand-tighten only using the recommended stylus wrench where applicable - do not over-torque the M2 thread. After installation, always re-qualify the stylus on the reference sphere before resuming measurement routines.
