Renishaw A-5000-3551 Cmm Ball Stylus 1mm M3 Ruby

Product Description

The RENISHAW A-5000-3551 is a CMM ball stylus designed for coordinate measuring machine probing applications. It features a 1 mm ruby ball tip mounted on a stainless steel stem with an M3 threaded connection. The overall length is 21 mm with an effective working length of 4 mm and a stem diameter of 0.71 mm. Ruby is the preferred ball material for CMM styli due to its hardness and wear resistance, making this stylus well-suited for high-cycle dimensional inspection work. Licensed metrologists, CMM operators, and quality control technicians are the primary users of this component.

This stylus is suited for precision dimensional measurement tasks on coordinate measuring machines in manufacturing, quality assurance, and inspection environments. Its compact 1 mm ball diameter makes it appropriate for probing small features, tight bores, and fine-detail geometry where larger styli cannot access. The M3 thread is a standard CMM stylus thread size compatible with a range of probe bodies and extension configurations used in both manual and CNC CMM setups.

Key Features

• 1 mm ruby ball tip for precise, wear-resistant contact measurement
• M3 threaded connection - standard CMM stylus interface
• Stainless steel stem with 0.71 mm diameter for rigidity in tight-access probing
• 4 mm effective working length supports small-feature inspection
• 21 mm overall length provides reach without excessive deflection risk
• Single-piece stylus construction - no sub-assembly required at installation

Compatibility

Designed as an OEM-style replacement or standard-service stylus for CMM probe bodies accepting M3 threaded styli. Consult your CMM probe body documentation to confirm M3 thread compatibility before installation.

Installation Notes

CMM styli are installed and serviced by CMM operators or metrology technicians. Power down or place the CMM in a safe parked state before changing styli to protect the probe head from impact damage. Use the appropriate stylus wrench or torque tool as specified by your probe body manufacturer - overtightening an M3 stylus thread can damage the probe body insert. After installation, perform a full stylus qualification routine on a reference sphere before resuming measurement programs.
