One continuous tension member for
matchless performance
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.
More power in less space
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.
Longer belt and sheave life
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 is 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.
Improve drive design while you reduce
drive cost
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.
Applications
For small sheave compact designs requiring limited vibration.
Ideal for high-speed ratio drives with short center distances.

Belts
One belt that can do the work
of many
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.
