Description
The ITP Straight Styli - Type J with a ceramic (aluminium oxide) ball is a compact, stemless stylus designed for precise probing in metrology and surface scanning. It’s ideal when a short, highly stable tip is needed for accurate measurements on challenging, abrasive surfaces.
- Tip material: Aluminium oxide ceramic ball for durability and wear resistance on abrasive, non-aluminium surfaces.
- Connection type: Direct base-to-ball construction with no stem for maximum stability and minimal deflection.
- Thread: M5 threaded connection on the top for secure attachment to measurement heads and fixtures.
- Overall length: 28 mm, offering a compact profile that enhances maneuverability in tight spaces.
- Type designation: Type J stylus (TIM518011028) designed for straight, short-length applications.
This straight, stemless design reduces mechanical play, delivering repeatable contact and consistent data during scanning and probing tasks. The ceramic ball provides a hard, smooth contact surface that stands up to repeated use on abrasive materials, while the direct base-to-ball connection helps maintain alignment and stability throughout measurement cycles. Compatible with standard M5 mounting systems, it integrates smoothly into existing metrology setups, enabling quick swaps without compromising accuracy.
