In terms of size alone, different manufacturers may produce the same product, but the material could vary. If they are from different manufacturers, you know
As long as it’s a manufacturer, they’re basically the same
Unpack and measure it; just treat it as surveying work
If there are sleeve spare parts available, just measure them directly; if there are shaft spare parts available, it’s also possible to measure the shaft diameter of the sleeve. If neither is available, as mentioned above, it might still be possible if they come from the same manufacturer, but it’s really hard to say in the case of different manufacturers
In theory, the initial design should be the same, but domestic manufacturers, in order to prevent competitors from copying their products and to gain control of the spare parts market – especially regarding sealing components – have altered the designs in various ways. It’s still more reliable to disassemble them and conduct detailed measurements
Logically, it should be the same, but people these days are too smart and know how to manipulate things.
