Jewel Bearing

Jewel bearings are a type of bearing that falls under the supply class Bearings, Plain, Unmounted in the supply group Bearings.

Jewel bearings are precision bearings that use jewels, typically made of synthetic sapphire or ruby, as the bearing surfaces. These jewels are highly polished and have extremely low friction properties, making them ideal for applications that require high precision and smooth rotation.

Jewel bearings are commonly used in instruments and devices that require accurate measurement or precise movement, such as watches, compasses, gyroscopes, and scientific instruments. They are also used in various industrial applications where low friction and high precision are essential.

The use of jewel bearings offers several advantages, including low friction, high durability, and resistance to wear and corrosion. They can operate at high speeds and provide excellent stability and accuracy.

Overall, jewel bearings are a specialized type of bearing that provides exceptional precision and reliability in various applications where smooth rotation and accurate movement are required.
