Spindle for LTK25:
3205, 3210, 3220, 3240

Design of nut for spindle:
3205 = F / FM
3210 = F / FM
3220 = F / FM
3240 = F
F = single nut / FM = preloaded double nut

Basic dynamic load rating of nut for spindle:
3205 = 24
3210 = 44
3220 = 42,5
3240 = 17
Dynamic load according to DIN 69, Part 4, issued 1978

Basic static load rating of nut:
3205 = 49
3210 = 53
