Stylus Anatomy 101
- Balls are grade 6 to 10, depending on diameter. Refer to our Technical Data for more complete information
- Available ball materials:
- Ruby / Sapphire (AL2O3, monocrystalline)
- Ceramic (AL2O3, polycrystalline)
- Silicone Nitride (available on request)
- Other materials are available
Ball / Shank Assembly:
Pivot Mount: A drilled ruby is glued to the reduced end of the pivot at shank end.
Solid Ball Mount: An undrilled ruby is glued directly to the end of the shank.
- 0.4mm and smaller diameter balls cannot be drilled for pivot.
- Drilled ball / pivot mount designs are recommended for 0.5mm and larger diameters for long life and durability.
Quick Reference Ball Diameter Coversion Chart:
|Small diameters||Lowest cost|
|Zero deflection||Great for high speed machines|
|Light weight||Lighter weight minimizes false triggering|
|Easy to see||Use for long configurations|
|Same Coefficient of Thermal Expansion as balls||Non-magnetic|
Standard Ferrule Designs:
- Short, conical
- Extended, conical
- No ferrule
PWMs diverse designs maximize strength, working length and assessibility according to your requirements.
