Overview
TAOMSUN precision ruby sapphire bearings are high-performance support components designed for low friction and high-speed operation scenarios. Made of artificial corundum (ruby/sapphire), with a Mohs hardness of 9, a surface roughness of ≤ 0.01 μ m, and a friction coefficient of approximately 0.14 with metals. The product includes 12 standard configurations in three series: through-hole (straight hole/arc hole, single/double oil groove), end face (flat end/ball end/cone), and groove shape (double ball). The outer diameter can be customized within the range of 0.8-6.0mm. ISO 9001 certification. Overseas technology is supported by METICULAB (South Korea).

❓ Frequently Asked Questions (FAQ)
Q: What are the advantages of arc hole design compared to straight hole design?
A: The design of arc-shaped holes can effectively reduce stress concentration at the edge of the hole, reduce the risk of cracking, and make contact with mating components smoother. Especially suitable for high-precision scenarios of high-frequency micro operation, it can significantly extend the service life of bearings.
Q: What is the function of a single oil tank?
A: A single oil tank can store lubricating oil and continuously provide lubrication during rotation, effectively reducing friction losses and extending lubrication maintenance cycles, improving equipment operating efficiency.
Q: What is the friction coefficient of this bearing?
A: When combined with steel, the friction coefficient is about 0.14, which ensures smooth operation at low friction and high speed.
Q: What is the standard size range?
A: Outer diameter: 0.8-6.0mm, thickness: 0.3-2.0mm, inner hole: 0.15-3.0mm, oil groove depth: 0.07-0.25mm. Non standard sizes can be customized.
Q: Can non-standard sizes or special oil tank designs be customized?
A: Okay. TAOMSUN supports customization of non-standard sizes, apertures, and oil tank geometries. Please provide CAD drawings or specification requirements, and we will provide you with a targeted quotation.
Q: How long is the usual delivery time for customized orders?
A: Standard inventory products will be shipped within 3-5 working days. Customizing specifications usually takes 2-4 weeks, depending on complexity and quantity.
