Sapphire Jewel with Cylindrical Hole, Without Cups

36500

High-precision bearing for fine mechanics

The sapphire jewel with a cylindrical hole and no cups is a key component of high-precision bearings. It serves as a support for a rotating steel shaft within a device, ensuring minimal friction and extreme wear resistance.

This jewel is designed to absorb both radial and axial loads, ensuring smooth and stable operation of the mechanism. It is often used in combination with a cap (support) jewel, where it helps maintain a constant axial distance, which is essential for the proper engagement of gear trains.
