Sapphire Cap Jewel, Polished on Both Sides

26200

High-precision bearing component for fine mechanics

The sapphire cap jewel, polished on both sides, is a key part of precision bearings. Together with a hole jewel, it forms a pivot bearing for gear trains, where its main function is to absorb axial loads and ensure smooth and stable movement of the mechanism.

Thanks to double-sided polishing, it achieves minimal friction, improving efficiency and extending the lifespan of the bearing system. Sapphire provides extreme hardness, wear resistance, and excellent stability during long-term use. This type of jewel is commonly used in watch movements, measuring instruments, and other precision mechanical assemblies, where high accuracy and reliability are essential.
