​​Custom Through-Hole Sapphire Bearings Precision Sliding Bearing​ Based on Drawings

A sapphire bearing is a precision sliding bearing that uses synthetic sapphire (single-crystal aluminum oxide, α-Al₂O₃) as its core material, formed through high-temperature melt growth and precision machining. With a Mohs hardness of 9 (second only to diamond), it exhibits an extremely low friction coefficient, excellent wear resistance, and strong corrosion resistance. Recognized as an ideal bearing material for instruments, control devices, and high-precision mechanical systems, it maintains long-term stable operation under harsh conditions such as high temperatures and strong corrosive environments.

Sapphire Bearings Key Data

1. Q: How does a jewel bearing work?

    A: A jewel bearing operates by allowing a metal spindle to rotate within a pivot hole lined with a hard gemstone material (like synthetic sapphire or ruby), which minimizes friction through its ultra-smooth, hard surface.

2. Q: What are the types of bearings?

    A:Bearings are primarily categorized into two main types: rolling element bearings (such as ball bearings and roller bearings) and plain/sliding bearings (like jewel bearings or fluid bearings), each designed to support different load directions and motion requirements.
