Description
The ITP Straight Stylus Type A with Silicon Nitride Ball is a rigid, reliable probing accessory designed for everyday measurement tasks. It’s ideal for technicians and engineers who need consistent contact and long life when scanning parts, especially those made from untreated aluminum.
- Ball material: Silicon nitride ball for excellent wear resistance and stable, low-friction probing contact.
- Stem material: Carbide stem delivers extreme rigidity to minimize deflection across a wide range of dimensions.
- Thread: M2 thread compatible with a broad range of tactile probes.
- Overall length: 52.5 mm, providing versatile reach in tight or constrained setups.
- Design: Straight Type A silhouette for straightforward alignment and repeatable results.
- Ball size availability: In this range, styli with balls from Ø1.0 mm to Ø5.0 mm are available; other sizes can be requested via the configurator or by e-mail.
- Ideal use: Specifically recommended for scanning untreated aluminum parts to balance accuracy and surface interaction.
Thanks to the carbide stem’s rigidity and the silicon nitride ball’s durability, this stylus minimizes measurement errors due to deflection or wear. The silicon nitride material is particularly gentle on untreated aluminum surfaces, helping protect delicate finishes while delivering repeatable results. With its 52.5 mm reach and standard M2 threading, it’s a practical, go-to choice for routine inspection, fixture validation, and product development workflows.
