There are also many manufacturers of a sapphire ball both in full and half sizes from Ruby, Sapphire, Ceramic and optical glass. Balls are manufactured as per AFBMA Grades and Tolerances. Such companies are among the very few manufacturers in the world who possess this technology. The various applications of a sapphire window are ball check valves, bar code scanners, bearing implementation and fiber optic connectors. These jewels as well as feed through insulator go through a special polishing process. These bearings are made in different sizes as per customer's requirement with and without spring as per customer's request.

The screws are made on Swiss screw machines to deliver highest level of accuracy and quality consistently. All the components of ball ruby are thoroughly cleaned before assembly and are assembled in absolutely dust free room. Ohmmeters, Voltmeters, Gauges, Compass, Timers, Relays, Ammeters, and Indicating Instruments are best known application where jewel bearings come into definite use for sure. A well-controlled process ensures proper edges for inflow of material, followed by a precisely centered and polished hole to ensure proper flow of water or air. A high degree of accuracy and precision is required in the manufacturing of these parts as they work under extreme pressure. These parts of a feed through insulator are manufactured as per customer's design and specifications. New entrants in this field can be helped by our engineering department to design nozzles to work under different pressure.
