all those machines take the same bearing the parts numbers you have are correct. the older 5 digit number had the better all metal bearings though unless you find those old stock youll only be able to get the new ones with the nylon ends.
ebay is your best bet. however if all your machines have thier existing bearings, remove them and re-grease them yourself. if the bearings are intact, you are wasting money buying new ones. they are 100% serviceable even with just a tube of grease and small flat blade screwdriver.
