TAOMSUN High-Hardness Conical Jewel Bearing – Corundum Ruby / Sapphire | Mohs 9 Precision Support for Instruments & Aerospace

Material: Synthetic corundum (Ruby / Sapphire / Al₂O₃) | Mohs Hardness: 9 | Origin: China | Korea Sales / Technical Support: METICULAB (Korea) | ISO 9001 · Precision Manufacturing

The TAOMSUN high-hardness conical jewel bearing is a key support component for instruments and precision equipment. It is manufactured from synthetic corundum (ruby / sapphire) with a Mohs hardness of 9 – second only to diamond – offering excellent wear resistance, high-temperature tolerance and mechanical strength. The conical structure distributes load more evenly, improving load-bearing stability; precision taper-angle machining ensures close fit with mating parts, enhancing positioning accuracy and reducing running deviation. It suits high-precision, high-reliability applications such as precision instruments, industrial automation, aerospace and medical devices.

🔍 Key Feature: Compared with flat-end or ball-end structures, the conical design distributes load more evenly and provides superior load-bearing stability, making it ideal for high-load, high-precision axial (thrust) support applications.

❓ Frequently Asked Questions (FAQ)

Q: What are the advantages of the conical structure compared with flat-end or ball-end structures?
A: The conical structure distributes load more evenly and effectively improves load-bearing stability; precise taper-angle machining ensures close fit with mating parts and higher positioning accuracy, especially suitable for high-load axial (thrust) support applications.

Q: What is the difference between ruby and sapphire bearings?
A: Both ruby and sapphire are synthetic corundum (Al₂O₃) with identical mechanical and chemical properties. The color difference comes from trace doping elements – ruby contains chromium, while sapphire is a pure crystal or contains other dopants. Both offer Mohs 9 hardness with the same performance.

Q: What is the friction coefficient of this bearing?
A: Approximately 0.14 against steel, which effectively reduces energy loss and extends equipment service life.

Q: What are the standard size ranges?
A: Outer diameter Φ0.8–6.0 mm, thickness 0.3–2.0 mm, bore Φ0.15–3.0 mm. The taper angle can be customized on request.

Q: Can you customize non-standard dimensions or special taper angles?
A: Yes. TAOMSUN supports customization of non-standard dimensions and taper angles. Please provide CAD drawings or specification requirements, and we will provide a targeted quotation.

Q: What is the typical lead time for custom orders?
A: Standard stock products ship within 3–5 working days. Custom specifications usually take 2–4 weeks, depending on complexity and quantity.
