- At speeds above 30 m/s, we recommend balancing the pulleys dynamically to grade q = 6.3 and higher.
- At speeds above 42 m/s, pulleys made of C45 steel, ductile iron GGG 40 or other higher quality material must be used.
On request, the pulleys can be balanced dynamically in two planes. Enter this request during the order in the "Note" field in the last step before sending it.
