Renishaw A-5003-0053 Cmm Ball Stylus 2mm Ruby M3

Product Description

The RENISHAW A-5003-0053 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 an M3 thread connection. The overall length is 40 mm (1.5748 inches), with an effective working length of 32.5 mm (1.2795 inches) and a stem diameter of 1.5 mm (0.0591 inches). Ruby is the preferred ball material for CMM styli because of its hardness and dimensional stability, making this stylus well suited for high-repeatability surface scanning and touch-trigger probing tasks. Installation and replacement are performed by metrology technicians and CMM operators in calibration labs and quality control environments.

This stylus is used in dimensional inspection setups where a small-diameter ball is required to access tight features, bores, or contoured surfaces. The M3 thread is a standard connection size compatible with Renishaw-style probe bodies and extension systems. It is appropriate for both manual and automated CMM probing routines in manufacturing quality control, tool and die inspection, and aerospace or automotive part verification workflows.

Key Features

• 2 mm ruby ball tip for high hardness and low wear in repeated contact measurement
• Solid carbide stem provides rigidity and minimizes deflection during probing
• M3 thread connection is standard across a wide range of CMM probe bodies and stylus changers
• 40 mm overall length with 32.5 mm effective working length for access to moderate-depth features
• Compact 1.5 mm stem diameter reduces obstruction in tight inspection areas

Compatibility

Designed as an OEM-style replacement stylus for CMM probe systems using M3 thread connections. Specific system compatibility should be verified against the probe body manufacturer documentation before installation.

Installation Notes

CMM styli should be installed by a qualified metrology technician or CMM operator. Power down or pause the CMM and retract the probe head before changing styli to avoid damage to the probe mechanism. Thread the stylus into the probe body by hand until snug, using only a stylus wrench if required - do not overtighten, as carbide stems and ruby balls are brittle. Recalibrate the probe qualification sphere after any stylus change to maintain measurement accuracy.
