Dia. 0.3Mm~30Mm Grade 5 Ruby Ball Bearing
The product is a grade 5 synthetic ruby ball bearing offered in diameters ranging from 0.3 mm to 30 mm. Each bearing is machined from synthetic ruby corundum (Al₂O₃) that provides a hardness of about 9 on the Mohs scale. The supplier lists the bearings as suitable for high‑precision applications where metal‑to‑metal friction must be avoided. The bearings are supplied individually, allowing custom quantity selection across the full size range.
In the precision engineering sector, ruby bearings of this grade are classified as Grade 5, meaning they meet the standard tolerance of ±0.001 mm and a sphericity error under 0.5 µm, typical for watchmaking and aerospace instrumentation. The synthetic corundum base gives a low coefficient of friction, generally below 0.1, and excellent corrosion resistance, which is why they replace steel pivots in environments with extreme temperature variation. Typical alternatives include ceramic silicon nitride, but ruby offers superior hardness and wear resistance for the smallest diameters.
Buyers such as watch manufacturers, medical device makers and aerospace navigation system integrators are the main market for these bearings. The supplier offers bulk packaging and can ship under FOB or CIF terms, though exact Incoterms and payment conditions should be verified directly. Prospective importers are advised to request the supplier’s material test reports and certification of grade 5 compliance before placing an order.

Sjllaser Technology Limited is located at Zhihui Building, Xinsha Road, Shajing Street, Bao'an District, Shenzhen 518104 Guangdong, China. The supplier holds a harbor trust tier, indicating a basic level of platform verification. No response rate or average response time is published, so buyers should initiate contact early to ensure timely communication.
The company presents itself as a technology‑focused manufacturer offering specialised synthetic ruby bearings among other precision components. While the profile mentions adherence to ISO 9001 quality management, the actual certification documents are not displayed and should be requested by importers before committing to purchase.
Grade 5 synthetic ruby ball bearings range from 0.3mm to 30mm in diameter and are manufactured from corundum gemstone material, offering exceptional hardness, abrasion resistance, and a low friction coefficient ideal for precision instrumentation. These ruby pivot bearings are widely used in watchmaking, medical devices, aerospace navigation systems, and high-precision scientific equipment where metal friction must be eliminated. As a specialized industrial bearing for export, synthetic ruby ball bearings serve a niche but critical role in global precision engineering supply chains.

Sourcing Dia. 0.3Mm~30Mm Grade 5 Ruby Ball Bearing from Sjllaser Technology Limited - China Import Guide
Importers should first obtain the supplier’s material test report and a certificate confirming Grade 5 compliance, as these documents verify that the bearings meet the stated hardness, tolerance and sphericity specifications. Because the supplier does not publish a response rate, establishing clear points of contact and confirming documentation availability early helps avoid delays.
Logistical details such as the preferred Incoterm (FOB or CIF), estimated production lead time and the shipping method (typically sea freight for bulk quantities) need to be confirmed with the seller. Payment terms, including any requirement for a letter of credit or advance T/T, should be agreed in writing before shipment to protect both parties.
Upon arrival, buyers are advised to perform a dimensional inspection using a calibrated micrometer, verify hardness with a Vickers tester if required, and review the supplied test report. A full inspection certificate, packing list and commercial invoice should accompany the shipment to ensure smooth customs clearance and traceability of the ruby bearings.
