Renishaw A-5000-7727 Cmm Stylus Extension M4 Ceramic

Product Description

The RENISHAW A-5000-7727 is a ceramic CMM stylus extension designed for use in coordinate measuring machine setups. It features an M4 female connection on one end and an M4 male connection on the other, allowing technicians to increase the reach of a stylus assembly without compromising rigidity. The ceramic stem provides a stable, thermally consistent shaft that minimizes measurement error caused by expansion. With a stem diameter of 7.40 mm and a 100 mm overall length, this extension is suited for probing deep features or recessed bores where a standard stylus cannot reach. CMM operators and metrology technicians are the primary installers.

This stylus extension is used in precision measurement applications on CMM equipment and machine tool probing systems. It is appropriate for both shop-floor and lab environments where repeatable probe positioning is required. The M4 thread standard is widely used across CMM stylus systems, making this extension compatible with a broad range of probe heads and stylus holders that accept M4 threaded connections. It is well suited for measuring deep pockets, recessed surfaces, and features that require extended probe reach.

Key Features

• M4 female to M4 male thread configuration for inline stylus reach extension
• Ceramic stem material provides thermal stability and low mass for accurate measurement
• 7.40 mm stem diameter balances rigidity with clearance in tight-tolerance probing
• 100 mm overall length extends probe reach for deep or recessed feature measurement
• Suitable for use with machine tool probes and CMM stylus systems

Compatibility

Designed for use with machine tool probes and CMM stylus assemblies using M4 threaded connections. No specific model compatibility data was provided in the product input.

Installation Notes

Installation is performed by metrology technicians or CMM operators. Power down or disable the CMM and any associated machine tool before handling probe components to prevent accidental triggering or damage. Thread the extension into the probe head or stylus holder by hand first, then snug lightly - do not overtighten ceramic components, as the material can crack under excessive torque. Verify stylus qualification after any extension change to maintain measurement accuracy.
