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.
