Belt characteristics
• Polyurethane t iming bel t wi th trapezoidal tooth prof i le
according to DIN/ISO 5296 with steel tension cords.
• Imperial pitch 7/8” = 22,225 mm
• Mainly used in applications where inch pitch is an advantage
(USA / UK)
• Width tolerance: ±1,0 [mm]
• Length tolerance: ±0,5 [mm/m]
• Thickness tolerance: ±0,4 [mm]
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:
