Series 28 Expanders
Wilson Combination Beading Expander

The Wilson Combination Beading Expander is one of our smartest tools! Rather than expand a tube, than manually bead it, and then re-roll it with a straight roll expander, the patented Combination Beading Expander (CBE) from Thomas C. Wilson does all three jobs in one seamless process.

And the Wilson CBE doesn’t just save time, cut labor costs and reduce your equipment investment: It produces a perfect bead every time! Designed primarily for the fabrication and re-tubing of fire-tube boilers, the Combination Beading Expander rolls and beads 2-inch, 2-1⁄2-inch and 3 inch Outer Diameter tubes, 10 to 13 gage.

The Wilson CBE for 2-inch Outer Diameter tubes is a 4-roll expander. For 21⁄2- inch and 3-inch tubes, it is a 5-roll expander. And the Combination Beading Expander is a self-feeding, parallel-rolling unit. For best results, trim the tube to be expanded and beaded to 3/16-inch projection.

To order, simply locate your tube Outer Diameter and Gauge. Each CBE assembly includes a standard mandrel, a grease gun (to lubricate the tool) and a service manual. You should order extra mandrels, straight rolls, beading rolls and guide roll assemblies, based on the number of tubes you will be expanding and beading. Your Wilson Product Application Specialist can help you determine how many spare mandrels, straight rolls, beading rolls and guide roll assemblies you should order. To prolong the life of your Combination Beading Expander, we recommend B-Kool.
