Renishaw A-5000-7811 Cmm Ball Stylus 1mm Ruby M2

Product Description

The RENISHAW A-5000-7811 is a precision CMM ball stylus designed for coordinate measuring machine applications requiring fine-detail probing. The stylus features a 1 mm ruby ball tip mounted on a solid carbide stem with an M2 thread for secure attachment to CMM probe modules. Overall length is 7.5 mm, and the stem diameter measures 0.71 mm, making this stylus well suited for accessing tight features and small bores. The ruby ball provides consistent wear resistance and repeatable contact performance. Calibration technicians, quality engineers, and CMM operators install this stylus in production metrology environments where dimensional accuracy is critical.

This stylus is used in dimensional inspection and quality control applications across manufacturing environments, including aerospace, automotive, and precision machining. Its compact geometry and M2 thread interface make it appropriate for use with standard CMM probe bodies that accept M2 stylus connections. The 1 mm ball diameter targets small-feature measurement tasks where larger styli cannot reach or maintain the required form accuracy.

Key Features

• 1 mm ruby ball tip for wear-resistant, repeatable contact in fine-feature measurement
• Solid carbide stem at 0.71 mm diameter provides rigidity with minimal deflection
• M2 thread interface for compatibility with standard CMM probe bodies
• 7.5 mm overall length suited for shallow-reach and tight-clearance probing
• Ruby point material resists wear over extended measurement cycles

Compatibility

Designed as an OEM-style replacement stylus for CMM probe modules accepting M2 thread ball styli.

Installation Notes

CMM styli should be installed by qualified metrology technicians or CMM operators following the probe manufacturer's torque and handling guidelines. Power down or pause the CMM and disengage the probe head before changing styli to prevent damage to the probe module. Avoid contact with the ruby ball during handling, as contamination or impact can affect measurement accuracy. Re-qualify the stylus on a reference artifact after installation to establish a valid calibration offset.
