| Dura-Belt Urethane Spool Flanges
are designed for use on powered rollers or other lineshafts that are
1.9” or larger in diameter. Our urethane’s supreme elasticity
holds them firmly in place. They stick so tightly to the shaft that
RAVE Ultra-Hold hair spray is necessary for installation, and when
dry, it acts as a glue that gives added protection against dislodgement.
If still more hold is desired, a drop of Loctite 480 will lock them
in place, but this is hardly ever needed. Our spool flanges are tapered
so that their outside edges do not rub against the belts, and they
rotate with the belts so no abrasion occurs. They also provide a little
extra drive. Mount them about 5/8” from a line perpendicular to the
powered roller and through the driven roller’s axis as shown,
or so the belt does not distort when touching the flange nor rub
on the outside edge of the flange. |
