Renishaw A-5000-7630 Cmm Ball Stylus 5mm Ruby M3

Product Description

The RENISHAW A-5000-7630 is a CMM ball stylus designed for use with coordinate measuring machines in dimensional inspection and quality control applications. It features a 5 mm ruby ball tip mounted on a stainless steel stem with M3 thread connection. The ruby point provides consistent, wear-resistant contact during repeated probing cycles, and the 2.5 mm stem diameter keeps deflection low during measurement. Overall length is 21 mm, making it suitable for standard reach probing tasks. Metrology technicians and quality lab personnel install and qualify this stylus as part of touch-trigger or scanning probe systems.

This stylus is used in precision metrology environments including manufacturing quality control, inspection labs, and production floor CMM setups. It is appropriate for residential and commercial manufacturing contexts wherever a 5 mm ruby ball, M3-thread stylus with a 21 mm overall length is specified. The effective working length of 21 mm and stem diameter of 2.5 mm make it a common selection for general-purpose dimensional probing on a wide range of part geometries.

Key Features

• 5 mm ruby ball tip for low wear and consistent contact repeatability
• M3 threaded connection for compatibility with standard CMM probe bodies
• 2.5 mm stainless steel stem for rigidity and low deflection
• 21 mm overall length suitable for standard-reach measurement tasks
• Stainless steel stem resists corrosion in typical lab and shop environments

Compatibility

Designed as an OEM-style replacement or standard-service stylus for CMM probe systems accepting M3 threaded ball styli.

Installation Notes

Installation is performed by metrology technicians or quality lab personnel qualified to work with CMM probe systems. Before changing styli, retract the probe to its safe position and follow the CMM manufacturer power-down or probe-lock procedure to avoid damage to the probe head. Thread the M3 connection by hand until snug, then qualify the stylus sphere using the machine's standard qualification routine before taking measurements. Avoid applying excessive torque to the M3 thread, as overtightening can damage the stylus stem or probe body.
