Belt characteristics
• Polyurethane timing belt with steel tension cords.
• Metric pitch 5 mm
• Tooth profile and dimension are optimised to guarantee uni-
form load distribution and minimum deformation under load.
• High resistance and low stretch steel cords to guarantee high
stability and low elongation
• Reduced polygonal effect with reduced drive vibration.
• Particularly suitable for linear drives and light power transmis-
sion applications with high axial and angular positioning accu-
racy.
• 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:
