2.2.3 Characteristics of the original belts

The standard belts on the market have different characteristics compared to the requirements of
the original spare belts, supplied by the authorised dealer. The latter are designed and manufac-
tured in close cooperation with the belt supplier and the machine manufacturer.
The table emphasises the reasons why it is important to choose an original belt, useful when mak-
ing such decisions.
Example
Adhesion on the
pulley.
Acceleration.
Length.
Floating pulley on
cutting equipment.
Curvature in two
directions.
Noise.
2 - INFORMATION FOR SERVICE CENTRES
Belts available on
the market
The belt rests with
the sides inclined
against the walls
of the pulley. There
must be a gap be-
tween the belt and
the bottom of the
groove.
Some belts only
engage with the pul-
leys when the motor
is running at operat-
ing speed and this
generates excessive
heat.
Manufactured in
standard interval
lengths.
Designed to trans-
mit power between
aligned, parallel and
fixed pulleys.
Designed to curve
around the pulley in
one direction.
Made without spe-
cial requirements for
this specific factor.
CHAPTER
Original spare belts
The belt rests with the sides
inclined against the walls of
the pulley. There must be a
gap between the belt and
the bottom of the groove.
The belt follows the speed of
the motor in continuous ac-
celeration until the maximum
speed is reached.
Made in a specific length
designed to ensure perfect
adhesion to the pulley.
The original Power Take
Off (PTO) belt is designed
to work even if the pulleys
move up and down and tilt at
the same time.
Most of the belts installed on
the machines have tension-
ing rollers that act on the
outer side of the belt. This
means that while the belt is
being used it must tilt both
inwards and outwards.
The original belts are care-
fully selected to limit the
increase in noise produced
by the machine during op-
eration.

Notes
Same requirements. The
original spare belts ensure
perfect adhesion on the
pulley.
Standard belts are made
of natural rubber and only
capable of withstanding
temperatures up to 70°C.
Original spare belts are
made of chloroprene rub-
ber capable of withstanding
temperatures up to 90°C.
The distance between the
pulleys is fixed. The belt
tensioner ensures that the
original belt maintains opti-
mal tension.
The equipment follows the
ground beneath it and this
means that the pulley is
constantly moving.
To withstand extreme oper-
ating conditions, the origi-
nal belts are made of fibre
reinforced rubber.
All the original belts, which
work with tensioning arms
acting on the external side,
are equipped with rein-
forcements.
The reinforcement is de-
signed specifically for these
specific cases.
Depending on the function,
one of the following belt
types is suitable:
• Coated
• Anti-friction
• Open sided
