Expander Collars – Up to 1” Outer Diameter
Thrust-Bearing Collars are assembly-furnished on all Expanders up to 1-inch Outer Diameter, except Wilson 72 and 73 Series Expanders, Gauge 20 to 23. Up to 15/16-inch recesses are available on request.
Deep-Recess Collars are available for the Wilson 72 and 73 Series Expanders and allow rolling on the far end where tubes project up to 3-inches (76.2mm). To order, specify “thin Gauge collar" and assembly number and required dash number - 7300 for 1-inch, 7200 for 2-inch and 7400 for 3-inch.
Close Collars offer optional collar assembly for rolling tubes too close to shell sides and divider plates to allow for the greater diameter of standard collars to pass. Close collars are available from flush to a 15/16-inch recess for all tube expanders offered.
