Dynamic Torque is calculated by:
[(AF x 0.5 (D-F)) / 2000]Nm or [(AF x 0.5 (D-F)) / 24]Lbft
(1) For discs outside the range, please call 1-888-547-DUKE (3853)

Static Torque is calculated by:
[(AF x 0.4 (D-F)) / 2000]KNm or [(AF x 0.4 (D-F)) / 24]Lbft
(1) For discs outside the range, please call 1-888-547-DUKE (3853)
