The hollow balls had very good advantage compared with the solid balls which had weight request application like the ball transfer unit for air cargo. We had over 15 yrs working experience on the hollow ball business with capability of producing carbon steel, stainless steel, aluminium hollow balls. The 1 inch hollow ball can bear over 6,000lbs load without crack, and are good at impacting load. With the hollow balls that we developed it can meet heavy load application while the cost is much lower than solid stainless steel balls. We had capability of producing hollow balls size small to 4mm with very good dimension control. If you are interesting you are welcome to contact us.
