Description
The ITP Straight Stylus Type A with Ruby Ball is a precision probing accessory engineered for long-reach measurements in CMM work and high-accuracy inspection. It combines lightness with exceptional rigidity to deliver stable contact and repeatable data, even at extended lengths. Product code TCM504011064.
- Dimensional spec: 64 mm overall length with an M5 thread for straightforward integration with standard probe systems.
- Stem material: Carbon fiber for a high stiffness-to-weight ratio, reducing deflection during probing.
- Ball diameter options: High-quality ruby ball available in sizes from Ø3.0 mm up to Ø12.0 mm to suit different contact geometries.
- Design intent: Straight configuration optimized for styli with excess length, providing stable contact and minimal bending under load.
- Customization: Other dimensions can be requested via the configurator or by email.
Thanks to the carbon fiber stem’s rigidity and lightness, this stylus minimizes deflection and vibration, supporting accurate touchpoints when measuring deep features or tall fixtures. The ruby ball delivers a hard, wear-resistant contact that maintains data integrity and reduces wear on workpieces. With a 64 mm reach and standard M5 threading, it integrates smoothly into existing probing setups, making it a reliable choice for metrology labs and precision manufacturing. If you need a different contact geometry, select from Ø3.0–Ø12.0 mm ruby balls or request alternate dimensions via the configurator or email to tailor the stylus to your exact inspection needs.
