Renishaw A-5000-8876 Cmm Ball Stylus 1mm Ruby M2

Product Description

The RENISHAW A-5000-8876 is a CMM ball stylus designed for use with coordinate measuring machines in dimensional inspection and quality control applications. It features a 1 mm ruby ball tip mounted on a stainless steel stem with an M2 thread connection. The overall length is 15 mm (0.5906 inches), and the effective working length is 8 mm (0.3150 inches). The stem diameter is 1 mm. Ruby is selected for its hardness and wear resistance, making it well suited for high-cycle scanning and touch-trigger probing on precision measurement equipment. This stylus is installed by metrology technicians and quality lab personnel.

This stylus is used in CMM applications requiring small-diameter access to tight features, fine bore measurements, and detailed surface geometry capture. The 1 mm ball diameter allows probing in restricted geometries where larger styli cannot reach. The M2 thread is a standard interface found on many CMM probe heads, making this a commonly specified replacement or supplemental stylus in production inspection environments, tool rooms, and quality assurance labs operating coordinate measuring equipment.

Key Features

• 1 mm ruby ball tip for wear resistance and dimensional stability under repeated contact
• Stainless steel stem provides rigidity and corrosion resistance
• M2 thread interface for compatibility with standard CMM probe modules
• 15 mm overall length with 8 mm effective working length for reach into confined features
• Compact 1 mm stem diameter supports access to tight geometric features

Compatibility

Designed as an OEM-style replacement or supplemental stylus for CMM probe systems using M2 thread connections.

Installation Notes

CMM styli are installed by metrology technicians following equipment manufacturer procedures. Power down or place the CMM in a safe parked state before changing styli to avoid damage to the probe head. Use the appropriate torque tool if specified by the CMM manufacturer - do not overtighten the M2 thread, as this can damage the stylus or probe module. Re-qualify the stylus after installation using the CMM calibration routine before resuming measurement.
