Sapphire Jewel with Olive Hole

36200

A key component of precision bearings for fine mechanics

The sapphire jewel with an olive hole is designed for high-precision bearings, where it serves as a support for a rotating steel shaft. This bearing absorbs both radial and axial loads, ensuring stability and long-term durability of the mechanism.

This jewel is often used in combination with a cap (support) jewel, where together they form a precise bearing system. In this configuration, they maintain a constant axial distance, which is essential for the correct engagement of gear trains. Thanks to the extreme hardness and durability of sapphire, the bearing operates with minimal friction and maximum stability, making it essential in aerospace instruments and other demanding applications.
