Precision Cone Pivots: Ruby Vee Jewels for the World's Most Sensitive Instruments
At the heart of every precision flow meter, pressure gauge, and ink jet printhead lies a pivot point that must resist wear over millions of cycles without a single drop of oil. The METICULAB™ Vee Jewel Bearing is that pivot — a single crystal synthetic ruby or sapphire cone ground to tolerances as tight as 0.004mm, providing the lowest possible friction torque for your most sensitive instrument designs.
