A bobbin mount is picked on three facts, and every one of the 735 listings on this shelf states all three: the configuration of its ends, the thread size and the maximum load in kilograms it will carry.
The configuration is the first split, and there are three. Male-male bobbins carry a stud at both ends, bolting machine to frame through clearance holes. Female-female bobbins take a bolt into each end, for blind fixings and easy removal. Male-female bobbins carry one of each, stud into the frame and bolt into the machine or the reverse, the general purpose form between them. The machine's existing fixings decide it: what is already there on machine and frame, clearance holes for studs or tapped holes for bolts, picks the configuration before anything else is measured.
The thread runs from M3 to M20 with M10, M8 and M12 the working centre of the range, and the load rating does the real engineering work: each listing states its maximum load exactly, from a few kilograms on the small M4 bobbins to hundreds of kilograms on the large forms, and the machine's weight divided by its mounting points gives the load each bobbin must actually carry, picked with margin and matched so the rubber works in the middle of its range, where it isolates best.
The size pairs in the codes read diameter and height in millimetres, so a worn bobbin measured across and along finds its own replacement directly, and thread plus load typed into search narrows 735 mounts to a workable handful.
