Pleiades is on a distinguished road
The bearing number is universal.

For example the Timken references are:

Upper: 32005X

Lower: 32006X

The KOYO (Yamaha OE) references are:

Upper: 32005X or JR

Lower: 32006X or JR

SKF are:

Upper: 32005XQ

Lower: 32006XQ

Looking forward to seeing the WP forks...
