One man's trash. ....

I got a 48" direct drive fan that way too, but I'm having trouble finding the correct bearings.

It works but after about 30 min you can't stand the dull howl anymore.

Thinking about converting it to belt drive and using an extra pool pump motor I have but the pulleys and bearings for that are over $75.

I couldn't find the bearings ether ! I pulled them out and brought them to the local bearing shop we mic ed it and found a replacement ! Had two do some slight honeing for the shaft holes but nothing major
