Renishaw A-5000-3552 Cmm Ball Stylus 2mm M3 Ruby

Product Description

The RENISHAW A-5000-3552 is a CMM ball stylus designed for coordinate measuring machine probing applications. It features a 2 mm ruby ball tip mounted on a stainless steel stem with an M3 thread connection. The overall length is 21 mm (0.8268 inches), with an effective working length of 9.60 mm (0.3780 inches) and a stem diameter of 1.27 mm (0.0500 inches). Ruby is the preferred ball material for CMM styli due to its hardness and dimensional stability, making this stylus well suited for high-repeatability surface contact measurements in precision metrology environments.

This stylus is intended for use in dimensional inspection and quality control applications where accurate point-contact measurement is required. It is compatible with CMM systems that accept M3-threaded stylus connections. Typical users include metrology technicians and quality engineers working in manufacturing, tooling, and inspection environments. The compact 21 mm overall length suits applications where clearance is limited or fine-detail feature access is needed.

Key Features

• 2 mm ruby ball tip provides hardness and wear resistance for repeatable contact measurements
• M3 thread connection for compatibility with standard CMM probe systems
• Stainless steel stem offers rigidity and corrosion resistance
• 21 mm overall length with 9.60 mm effective working length for close-clearance access
• 1.27 mm stem diameter balances stiffness with minimal deflection

Compatibility

Designed for use with CMM probe systems that accept M3-threaded styli. Confirm thread type and stylus holder compatibility with your specific CMM system before installation.

Installation Notes

CMM styli should be installed and removed by qualified metrology technicians using appropriate stylus wrenches to avoid overtightening or cross-threading the M3 connection. The CMM should be powered down or the probe held in a safe parked position before changing styli. Avoid touching the ruby ball with bare hands, as skin oils can affect surface cleanliness and measurement accuracy. Re-qualify the probe after any stylus change per your CMM manufacturer's calibration procedure.
