The Poly-V belt is a single, endless belt with longitudinal
V-shaped ribs that mate consistently with the V-grooves in the
sheaves. It combines the convenience of a thin, one-piece flat belt
with the strong gripping traction of multiple V-belts to make the
Poly-V belt far better than either for many applications.

To distribute the drive load evenly across the full width of the
sheave, the Poly-V belt is built as a single unit with a completely
supported, uninterrupted tension member. There is no matching
problem. No separate belts to turn over, grab, slip, or interfere with
each other.
The thin cross section profile allows use of smaller pulleys than
standard V-belts, and Poly-V belts handle speed ratios of 40:1.
With all this capacity, the Poly-V belt tracks properly without
special guides, flanges, crowns or deep grooves. And it resists
seating in the grooves, so speed ratios remain more consistent and
output speed remains more uniform.

Continuous engagement with the sheave driving surface gives
you greater power capacity per inch of width. In addition, wasted
space between separate V-belts is eliminated and converted into
narrower, shallower grooves. These provide substantially greater
contact area for stronger and more uniform traction.

Complete support of the tension member, combined with full
and uniform engagement with the sheave grooves, eliminates
differential driving and equalizes belt stresses. That, in turn,
minimizes belt elongation and leads to significantly longer flex life.
Even distribution of stress on the belt also reduces differential
loading and wear on sheaves. It’s not unusual for Poly-V belt
sheaves to last significantly longer than standard V-belt sheaves
and to experience lower maintenance requirements during this
longer life.

The combination of high-power capacity and low-profile design
means the Poly-V drive can improve the drive design while
lowering drive costs.
Poly-V belts allow narrower mounting clearances, need less center
distance adjustment, and require less take-up for tensioning.
Additionally, they allow the use of sheaves that are narrower in
width and smaller in diameter without sacrificing power capacity.
Smaller, narrower sheaves mean a reduction in weight so more of
the drive gets to the load for increased efficiency.
