There isn't a set dimension for that on trailers. Typically axles are custom ordered to the specs needed. They order the spring seat to seat dimension for mounting to the trailer and then the hub face to face dimension for what will clear the fender wells.

For example, we have the 3,500 lb trailer axle part # T3584F-EZ-8974 which has 89 inches from hub face to hub face and then 74 inches from spring seat to spring seat.
