vee jewels

Vee Jewels

Vee Jewels are well suited to sensitive instruments where the moving element is light. They offer minimum friction when used with conical, small radiused pivots and permit slight lateral movement. The jewel radius should be 3 times larger than the pivot radius for low friction torque, sensitivity, and resistance to deformation. The contact area of the pivot should be highly polished and a micro-inch finish of 2 or better on the pivot radius is recommended.  Typical applications include Ohmmeters, Voltmeters, Gauges, and other Indicating Meters, Compass, Timers and Relays.
