Design Recommendations |
- Gates Mectrol flat belts have
very high strength and extremely low stretch.
They are designed to be run on flat faced
pulleys with flanges. Crowned pulleys should
not be
used.
- Gates Mectrol flat belts are not
recommended for applications which involve
belt twisting. Should an application
require that a belt be twisted 90°, the length
over which the twist occurs should be a minimum
of 15 inches for a one inch wide
belt
- Gates Mectrol flat belts are not
to be used in "lat" pull down
fitness machines or other machines in which
belt twist is unrestricted.
