Jewel bearings are also employed extensively in sensitive measuring equipment. They are normally applied in very petite uses, like high-precision instruments. These include energy meters, water meters, marine compasses, gauges, voltmeters, temperature controller, aircraft instruments, flow meters, etc. 

Types of Jewel Bearings: Ring Jewel bearings, Vee jewel bearings, Cup jewel bearings, End stone bearings, Cylinders Rods, Balls

Cup bearings are jewel bearings that fit a ball bearing between two-cup jewels or semi-spherical pivots. They are often used in vertical shaft applications, such as compasses and heat monitors. V-bearings are jewel bearings that are suitable for sensitive magnetic meter movements, compasses, encoders, turbine flow devices, and galvanometers. Unlike a miniature bearing that uses line contact, a V-bearing provides a low-friction coefficient because its moving shaft is near the point of contact. Glass V-bearings have slightly lower friction because their surfaces are fire polished. Synthetic jewel bearings, jewels, and pivots are sometimes selected because of their superior hardness and ability to accept a high polish.

Ring jewels are journal or annular bearings that contain a contoured hole shaped like an hourglass or an olive, rather than a straight cylindrical bore. The advantage of ring jewels over conventional bearings is that a ring jewel provides a reduced contact area that causes lower friction between the shaft and the bearing. Ring jewels are commonly found in instruments such as watches, dial indicators, and gimbal suspensions.
