If something goes wrong, it goes really wrong.
I ordered the RULAG35PH bearing, but received a gray plastic shaft bearing from CARAVEL with the same part number, which I immediately returned.
After numerous phone calls with sales and the warehouse, I finally received the RULAG35PH (which was ordered as a special order from Vetus, even though the online shop consistently showed 3 units available) after more than three weeks.
Long story short – when the data in the catalog, online shop, and warehouse isn't consistent, things can go very wrong.
I've now installed the bearing, and the shaft runs very smoothly.
