   A half ball has a flat base and a curved surface that forms a semicircle. Half balls are commonly used in various applications, such as in jewelry making, optical lenses, flow control valves, and measurement instruments. They can be made from a variety of materials, including glass, metal, plastic, and ceramics.

   The precision of half balls can be important in some applications. The AFBMA (Anti-Friction Bearing Manufacturers Association) sets standards for the manufacturing of precision balls, including half balls. The sizes and tolerance grades for half balls are similar to those for balls and can vary based on the specific application.

   We can reach the groundness precision to Grade 3

   Each ball is checked 100% for size accuracy & polish aspects before delivery. Customized packaging options are available as per customer’s needs.

Glavna aplikacija

Optične leče:Half balls can be used as optical lenses, where the curved surface of the half ball can refract or focus light. This application is used in cameras, microscopes, telescopes, and other optical devices.

Ventili za regulacijo pretoka:Half balls can be used in flow control valves, where the half ball rotates to open or close the valve. This application is used in piping systems, such as in the oil and gas industry.

Merilni instrumenti:Half balls can be used in measurement instruments, such as force sensors, where the deformation of the half ball under a load can be measured to determine the applied force.
