Renishaw A-5000-4160 Cmm Ball Stylus 3mm Ruby M2

Product Description

The RENISHAW A-5000-4160 is a CMM ball stylus designed for coordinate measuring machine probing applications. It features a 3.00 mm ruby ball tip mounted on a stainless steel stem with an M2 thread interface. The overall length is 20.00 mm, with an effective working length of 17.00 mm and a stem diameter of 1.50 mm. Ruby is the preferred ball material for CMM styli because of its hardness and dimensional stability, which supports repeatable contact measurements. This stylus is installed and qualified by metrologists and CMM technicians in quality control, inspection, and manufacturing environments.

The A-5000-4160 is suited for use in tight-clearance and general-purpose CMM probing setups where a small-diameter ruby ball and compact overall length are required. The M2 thread allows direct mounting to compatible Renishaw probe modules and extension bars. Typical applications include dimensional inspection of machined parts, bore measurement, and surface profiling in both shop-floor and laboratory CMM installations.

Key Features

• 3.00 mm ruby ball tip for hard, dimensionally stable contact measurement
• Stainless steel stem resists corrosion and provides rigidity during probing
• M2 thread interface for direct mount to compatible CMM probe bodies and extension bars
• 20.00 mm overall length with 17.00 mm effective working length for compact reach applications
• 1.50 mm stem diameter minimizes deflection in standard probing cycles

Compatibility

Designed as an OEM-style replacement or standard-fit stylus for CMM probe systems using M2 thread connections. Specific system compatibility should be verified against the probe module and stylus rack configuration in use.

Installation Notes

CMM styli are installed and qualified by trained CMM technicians or metrologists. Before replacing or mounting a stylus, power down or pause the CMM and disengage the probe head per the machine manufacturer's procedure. Use a calibrated torque tool if specified by the CMM manufacturer - do not overtighten the M2 thread, as this can damage the stylus seat or probe module. After installation, perform a full stylus qualification routine to establish accurate tip-center offset values before resuming measurement programs.
