Bending Shoe Radii Table for
Benders on pages 14 - 41
These radii tables are provided for your general information. The
Centerline and Inside radius are shown for each shoe.
In selecting a bender set, compare the shoe model numbers shown in
the bender selection charts to these tables for complete shoe
radii information.
Three bending shoe tables are shown:
1. For thinwall (EMT) conduit. See chart on page 45.
2. For IMC conduit and pipe. See chart below.
3. For steel and aluminum rigid conduit and pipe. See chart on
page 46.
(Bending shoe tables for Eegor™ hydraulic benders are on page 11,
for Mini-Eegor™ hydraulic benders see page 13.)

Mini-Eegor ™ Radii Tables
These radii tables for EMT, IMC and rigid conduit are provided for
general information. The centerline and inside radius are shown for
each shoe.
In selecting a bender set, compare the shoe model numbers shown in
the bender selection charts to these tables for complete shoe
radii information.
Lubricate rollers, when needed, with molybdenum disulfide paste only
(such as Dow Corning’s Molykote #G-n paste, or equivalent.)
For heavy use, lubricate rollers weekly.
Note:
Graphite formulations are not equivalent lubrications.
* Actual bend radii are slightly larger because of pipe springback.
