Belt characteristics
• Polyurethane timing belt with round tooth profile and high ten-
sile load tension cords. Produced according to ISO 13050
• Metric pitch 8 mm
• The round tooth profile allows a uniform load distribution that
guarantees high performances, high transmissible torque and
precise tooth engagement.
• Widely used in linear positioning, medium power transmission
applications.
• Width tolerance: ±0,5 [mm]
• Length tolerance: ±0,5 [mm/m]
• Thickness tolerance: ±0,2 [mm]

Load / Elongation [ % ]
Tooth shear strenght / rpm
The specific load F
Uspez
is the maximum load which one single
belt tooth 1 cm wide can withstand in all operating conditions.
This force is related to the drive rpm.
The total load F
U
transmissible by the belt in the dr ive is
calculated by:
