ROBUS in-line helical gearbox

code system

1.    first 4 digits describe the ROBUS size
RB40 = ROBUS 40
RB50 = ROBUS 50
etc
2.    then 1 digit tell the nr of stages
2 = 2 stages
3 = 3 stages
3.    then 3 digits are the rated ratio
020 = i:20
120 = i:120
etc
4.    then 3 digits for the mounting type

FSW = base type SW
FBF = base type BF
FMS = base type MS

140 = output flange 63B5 KP=140
160 = output flange 71B5 KP=160
200 = output flange 80/90B5 KP=200
250 = output flange 100/112B5 KP=250
300 = output flange 132B5 KP=300
350 = output flange 160/180 KP=350
450 = output flange 200 KP=450

UNV = without foot or output flange
 
5.   then 3 digits for the input flange (that
determines the input hole diameter too)

714 = 71B14
805 = 80B5
905 = 90B5
125 = 100-112B5
135 = 132B5
etc
