I’m not aware of any public sites that have cross references across all the brands, the best way is to have your local bearing distributor do the work for you. If you want to do that yourself, usually you need to go to a manufacturers site and use their cross reference, or you can use the dimensions of your bearing and find the part number in each manufacturers catalog. Keep in mind, not many companies make inch sized tapered roller bearings, so your selection is not going to be very large.
If you put your bearing number into one of the distributors online catalogs, you’ll see who makes a TRB in that size and can then dig down into the details of the part number to see if they are identical. You’ll see a lot of them will say call for price, that usually means it’s not a stocked item and they’ll have to see where they can get one. Inch bearings are not used much in new equipment, so manufacturers may only do a small run once in a while on the less popular sizes, so it can be hit or miss on availability. The same is true of metric bearings, but more so with inch due to the lower demand.
