Jewel And Screw Assembly

Jewel and Screw Assembly is a type of component used in various instruments and laboratory equipment. It is classified under the supply class Combination and Miscellaneous Instruments, which is part of the supply group Instruments and Laboratory Equipment.

The Jewel and Screw Assembly typically consists of a jewel bearing and a screw that are combined together to provide smooth and precise movement in instruments such as watches, compasses, measuring devices, and scientific instruments. The jewel bearing, usually made of synthetic ruby or sapphire, acts as a low-friction pivot point for the screw, allowing it to rotate smoothly and accurately.

This assembly is commonly used in instruments that require precise measurements or movements, as the jewel bearing reduces friction and wear, resulting in improved accuracy and longevity of the instrument.

Overall, the Jewel and Screw Assembly is an important component in Combination and Miscellaneous Instruments, providing reliable and precise movement in various instruments and laboratory equipment.
