Radii Tables
These radii tables for EMT, IMC and rigid conduit 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.
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 lubrication.
* Actual bend radii are slightly larger because of pipe springback.
