The weight savings inherent in hollow steel balls makes them an
excellent
choice for the ball transfer units used in material handling, cargo
shipping,
assembly, and other applications where loads must be transferred
smoothly,
and with minimum deviation. The hollow ball takes the place of a
solid ball
and provides a significant weight savings. As one example, a hollow
ball
weighs 44 grams less than a 1” solid ball, providing a weight
savings of
more than 65%.
