(1) SF suffix indicates solid shaft -- the 42 size is available only with ratio 1 and solid output shaft.
(2) WS42SF ratios -- L1(1stage): 4,5,7,10; L2 (2stage): 12,15,16,20,21,25,28,30,35,40,49,50,70.
(3) F suffix indicates Hollow shaft is standard. However, "solid output shaft" and "double output shafts" are regular options.
(4) WS 70 to WS150 ratios -- L1(1stage): 6,8,10,14,20 ; L2 (2stage): 18,24,30,32,40,42,50,56,60,70,80,98,100,140,200
Please inquire for any ratio not shown.
(5) At 3 % of rated load.
(6) At a distance of one-half of one coupling length -- from end of the coupling.
