Delta 50-851 Bearings

Go ahead and disassemble it and replace them now. With the old ones in hand you’re sure to have to correct ones from the bearing shop in the middle of a project. That beats having them seize in the middle of a project, besides you could get some collateral damage waiting for them to fail.

You can clean them. They’re probably sealed, so pry the seals off and soak them in some naphtha for a while. After that, I hit them with compressed air and a couple of dollops of white grease and replace the seals.

As Fred suggested, go ahead and measure them while they’re out. I bought mine for my bandsaw on Grainger.

Looks like I’ll have to take them apart; Delta was no help unfortunately. I’m mid-project at the moment, so I’m weighing having them go mid-project verses being idles mid-current-project. Thanks for the perspective.

I think I’ll go the replacement route; new bearings are well within the budget, and I rather not risk them going all Damocles after I’ve put in the work to dis/reassemble.
