WOOD SAWYER BAREBACK CONVEYOR BELT DATA - Imperial
Wood Sawyer P/P rated belt tension can exceed 100%, with a maximum of 150%, during starting and stopping conditions.
Fastener size recommendation may vary due to cover thickness.
*
P/P = Polyester/Polyester
**
Average permanent elongation values at 100% of rated belt tension are based on ISO 9856 test procedure. Consult your GTM or GAD for elastic & total elongation calculations specific to each system
based on Minuteman calculations.
Additional break in time is required when the belt has been stored prior to installation in ambient temperatures of less than 10 degrees Centigrade.
