c) Pull the belts according to manufacturer instructions. Excessive pulling can cause reduced bearing life
and wear out the pulley prematurely. Pulling depends on different variables as indicated in point 9.12.
d) Belt length has a natural tolerance ≥ ± 0.75%. For this reason, the 3 belts must be purchased as a pair.
e) Follow the direction of the belt pull as shown in fig. 10; for other needs, contact our Customer Service
Department.
f) Take care of the alignment of the driving pulley and driven pulley grooves.
9.12 Definition of static pull to apply on belts
Static pull depends on:
a) The wheelbase between the two pulleys (belt length)
b) The load due to static pull of the belt
c) The number of belts
d) The winding angle of the smallest pulley
e) Average speed
f) etc.
Values of the static pull to be applied can be obtained from the diagram in fig. 11 for belts with a XPB profile in relation
to the wheelbase.
