Bender Construction
Each bender consists of a cast aluminum frame and
base, with a manual crank-operated steel worm gear
mechanism. A 60:1 ratio enables the operator to make
bends up to 180° in one continuous smooth operation
without strain or fatigue. Center drive shaft and worm
gear shaft are supported with pre-lubricated ball bear-
ings. The worm gear has a ball-type thrust bearing, and
is completely enclosed for safety and protection from
external damage. The main base of the benders has a
square base for clamping in a vise or each bender can
also be mounted in an adapter unit and fastened to a
workbench.
