Belt characteristics
• High performance polyurethane timing belt with HPL steel ten-
sion cords.
• Metric pitch 20 mm
• Specially designed for linear drives
• Tension cords with increased allowable tensile load compared
to standard for lower elongation.
• Produced with special pretension and pitch tolerance to gua-
rantee high positioning precision in linear drives.
• Width tolerance: ±1,0 [mm]
• Thickness tolerance: ±0,4 [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:
