Features
FHP V-BELTS
Bando FHP V-Belts are built for maximum tension
control, drive uniformity and long life, with minimum
heat build-up and stretching on low horsepower electricmotoros and gasoline engines. They are designed
for high speed and short center distance.
MULTIPLE V-BELTS
For multiple drive, high speed and high torque drives
on light or heavy industrial or automotive machinery.
Bando Multiple V-Belts have exceptional length stability
and drive uniformity. Rigorous testing has shown these
Premium Quality Belts to have twice the service life and
significantly greater transmission capacity than most
other multiple V Belts.

٨ Designed specifically for reverse-bend drive by
positioning tensile members closer to the neutral axis
and by making the belt thickness a little thinner than
that of Conventional Multiple V-Belts A, B, & C Sections.
٨ Particularly suitable to agricultural machinery such as
combine harvester and garden tiller where belts are
often driven with backside idler.

Making full use of the capabilities of agricultural
machinery
As the agricultural machinery increasingly enhances
its performance and functions, the quality required
for V belts used in the agricultural machinery is going
upscale.
On fine quality market, there are cases where the
agricultural machinery should use more than the RED-S
㸈 in order to deliver the thorough functions. Now, we at
BANDO launch the Series W800 of the highest quality
among V belts (Series W) for the agricultural machinery
use on the fine quality market.

The Series W800 has heat and flex resistance superior
to any other V belts, which makes it a top-end V belt
for the agricultural machinery use enabling high-load
power transmission. You can be assured to use this V
belt under harsh environments.

Features + Benefits
٨ Designed for reverse-bend ser pentine drives by
covering the belt with special woven fabric.
٨ New Cross Section for maintaining proper belt position
in pulley groove even in the case of extreme reversebend drives.
٨ Due to greater flexibility created by the special woven
fabric as well as to the New Cross Section, service life
has increased by about 40% over that of traditional
double V-Belts.

The superior power transmission capacity of the Bando narrow Power Ace® V-belts allows for drive designs with
smaller components reducing machine space and cost. The higher efficiency of the Power Ace® V-belts will also result
in decreased operating costs.
