Sapphire Jewel with Cylindrical Hole

36100

Precision bearing component for fine mechanics

The sapphire jewel with a cylindrical hole is a key part of high-precision bearings, serving 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 maintain a constant axial distance, which is essential for the precise engagement of gear trains. Thanks to the extreme hardness and wear resistance of sapphire, it provides minimal friction and excellent bearing stability, making it essential for aerospace instruments and other precision mechanical systems.
