Product Details
This precision ball stylus is designed for high-accuracy probing applications on coordinate measuring machines (CMMs). The Ø1.0 mm ruby ball provides excellent hardness and wear resistance, making it ideal for measuring small or delicate features with high precision and minimal contact force.
The stylus is mounted on a stainless steel (SS) stem, offering strength and rigidity for stable probing operations. With an overall length of 19.5 mm and an effective working length (EWL) of 4.5 mm, it provides a compact and stable configuration suitable for precision inspection tasks.
This component is well suited for metrology applications requiring fine feature access, durability, and consistent measurement accuracy.
