Renishaw A-5555-0060 Cmm Ball Stylus 2mm Ruby M5

Product Description

The RENISHAW A-5555-0060 is a CMM ball stylus designed for coordinate measuring machine applications requiring precise, repeatable point contact measurement. It features a 2 mm ruby ball tip mounted on a solid carbide stem with an M5 thread interface. The overall length is 58 mm (approximately 2.28 inches), with an effective working length of 33 mm (approximately 1.30 inches) and a stem diameter of 1.50 mm. Ruby is the preferred point material for CMM styli due to its hardness, low friction coefficient, and dimensional stability. Metrology technicians and calibration professionals install this stylus on CMM probe heads for dimensional inspection work in manufacturing and quality control environments.

This stylus is suited for residential and commercial metrology applications where a small-diameter ball is needed to access tight features or measure small bores. The M5 thread is a widely used CMM interface, making this stylus compatible with a broad range of probe head systems. Typical applications include surface profiling, bore measurement, and feature inspection on precision machined parts. The compact ball diameter of 2 mm allows access to fine geometric features that larger styli cannot reach.

Key Features

• 2 mm ruby ball tip for hard, low-friction point contact and long service life
• Solid carbide stem provides high stiffness and minimizes bending error during probing
• M5 thread interface compatible with standard CMM probe head connections
• 58 mm overall length with 33 mm effective working length for reach into moderate-depth features
• 1.50 mm stem diameter balances rigidity with clearance in confined measurement areas

Compatibility

Designed as an OEM-style replacement stylus for CMM probe heads accepting M5 threaded styli.

Installation Notes

CMM styli are installed by metrology technicians and calibration professionals. Power down or pause the CMM and retract the probe head to a safe position before changing styli. Use the appropriate stylus wrench or torque tool recommended by the CMM manufacturer to avoid overloading the probe head thread. Handle the ruby ball carefully, as impact damage to the ball will compromise measurement accuracy and require replacement.
