Deep groove ball bearing 6404. Under GOST the same bearing is designated 404.
M: M.G.M. data. Another brand publishes its own figures, so compare them against that brand’s catalogue.
It is the same bearing under GOST 3189-89: 404 corresponds to the ISO base 6404. Size 20 × 72 × 19 mm, a full equivalent of 6404.
Same size, clearance greater than normal. C3 is used where the bearing runs hot or sits on the shaft with an interference fit. If the old bearing is not marked C3, take this one.
Without checking, only an exact equivalent: the size, seal, clearance and design match according to the brand’s catalogue. Positions with the same geometry differ in seal, clearance or design, and each one says so in the equivalents block. Load ratings differ between manufacturers, so for a heavily loaded unit compare C.
