Custom Ball-O-Matic equipment available:

National Ball-O-Matic offers a horizontal machine that can finish a 16 foot long tube with a 2" I.D., thus eliminating some very expensive honing. The tube is hand loaded into a retaining nest that keeps it straight during the ballizing operation. The retaining nest corrects part of the camber (bowed condition) of the tube during ballizing. This is a self-contained hydraulic unit that conserves floor space. The variable pump from 0-3,000 P.S.I. has speed controls for the ballizing ram. The ball track can be changed according to your specifications on a machine like this, ranging from 2" to 6" I.D.

A Shock Absorber Tube Sizing Machine

is another special item developed by national Ball-O-Matic. Production rate is 4 tubes in 4-1/2 seconds. The hot work-hardening effect of ballizing strengthens the wall of the tube, increases the wear life of the shock absorber and improves the micto finish to 5-10 R.M.S.
