Hi Guys,
In case you are shopping for idler and tensioner bearing for your timing belt (3rd gen 3S-GTE), the 2 bearing are the SAME.
Tensioner (bearing, frame, bolt, washer) 13505-88480 - €123,
Idler (bearing only) 13503-63011 - €58 incl. VAT from Toyota
The bearing is Koyo PU355816RR9D
Obviously if you buy 2 Koyo PU355816RR9D, you will reuse the tensioner's frame, bolt and washer.
The above mentioned bearing is not a "compatible" one, it is the very same one you get from Toyota.
If you order Blueprint ADT37616, the same Koyo bearing will be on the frame ready to install for around €40 instead of the €123 from Toyota.
In case everybody knew it, and I'm the last in the world to find it out, please let me know

If you didn't know and it helps, also let me know.
Cheers
