Ruby Jewel Bearing

ruby jewel bearing
Ruby jewel bearing have been used ever since the year 1704 in mechanical watches.

All kind of high-quality mechanical watches uses the ruby jewel bearing for long life and precise time. It can be commonly seen in skeleton movement watches as pink or red colour bearings and are often interpreted to exhibit the higher value of the watch.

Ruby material used by us is a factory-made single crystal from AL2O3[aluminium oxide ]. This material is pink or red in colour depending on its colour grade. The red colour in this material is obtained by adding oxides such as chrome during the manufacturing process.

Industrial jewels have been making these ruby jewel bearings with Swiss know-how and experience of over 50 years and supply them to world-renown watchmakers and industrial movement makers around the globe.

The hardness of ruby jewel bearing is 9 on the MOHS scale, which is next hardest to diamond which has hardness 10 on the MOHS scale. This makes the ruby jewel bearing the hardest bearing for industrial applications with cost-effective pricing. Because of extreme hardness, the ruby jewel bearing can attain an extremely high-level polish with the surface finish as good as 0.025µm.

With a melting point of over 2000 degree Celsius, the material can withstand temperature as high as 1000 degree Celsius without any effect on its crystalline structure.

Micro precision products which need long life expectancy along with very high reliability and precision are ideal applications for the ruby jewel bearing. Due to high polish level [resulting in lower friction] and good temperature stability, the jewel bearing is commonly used in a wide variety of industrial applications which required very low friction along with consistency in performance and long life.

These parts are manufactured in micron tolerances and measured on the most reliable and accurate Swiss measuring instruments. Each ruby jewel bearing is checked 100% under the microscope to ensure the quality and reliability of the product.
The statically controlled and monitored manufacturing process ensures a high degree of product reliability which involves quality checks at each step of manufacturing as per customer’s specified AQL levels. Industrial Jewels have a completely integrated ERP system which ensures full traceability of the material from the raw material stage to the finish products.

The ruby jewel bearings can be customized as per customer’s drawing, design and specifications. We closely work with our customers to help them design a precise, reliable and cost-effective product. For test production we also manufacture pilot lots of as small as, lot size of 50 pcs until mass production involving several million pcs.
