Series 65 Expander
Series 65 Expander

This expander is primarily intended for deep reach expanding. Its parrallel rolling and long effective roll length make this tool ideal for "touch up" rolling in thick tubesheets.

A thrust ball bearing collar gives friction-free operation and long tool life. Rolls are self retained in cage and will not fall in or out of cage when mandrel is withdrawn from expander.
