STAINLESS STEEL/METALLIC ALLOY HOLLOW BALLS

Hollow balls manufactured in different materials, they allow to get a remarkable weigth saving and keep the properties of the correspondent solid balls (mechanical properties, corrosion resistance, magnetism). Balls are hand made (welding plus polishing), this is the reason when precision grade is not high.
Applications
Special valves, ball transfer units, conveyor belts, magnetic devices, floating devices, calibration instruments, ornamental applications (internal and external decor), cosmetic rollon.
