features:
Rolls and beads in one operation.
No need for beading tools or air hammer.
No operator fatigue caused by continuous use of air hammers.
No need to re-roll after completion as with manual beading.
Use:
The Combination Beading Expander comes in three sizes, 2.0", 2.1/2" and 3.0" OD.
NOTE: You only need to replace the Beading Roll and the Guide Roll assembly to change tube wall thickness.
The Powermaster Industrial Combination Beading Expander is is a leader in saving time and reducing operator fatigue. The quality of the bead is consistent around the tube edge with no ridges as in air beaded tubes which can cause cracking on the bead by over working it. As seen below:
The above images are of 2.1/2" 11 BWG tubes we rolled with a total of 104 tube ends. The whole installation was completed in one day including hydro test. The rolling motor used had the capacity for 3.0" tubes. W can't stress enough the key to this operation is proper lubrication to conquer the inherent heat build up from friction within the tool. As a lubricant we used our own Lube Right developed here in Canada for the expansion of tubes.
