Spindle Bearing Replacement For The Rf-31 Mill/drill

[Canuck75]

Mikey & Canuck75, thank you for this thread.

A question for both of you;

How are the bearings performing in both of your mills?

I have a Central Machinery, Chinese, Grizzly G0705 copy that I bought new from a guy that never used it. I stole it for $500.

I am surprised at how good the quality is, but I am looking at doing this bearing replacement.

Thanks guys!

Techee, sorry about the time delay but have just looked back at this thread. Like Mikey, I too am very pleased with the double sealed angular bearings. No issues whatsoever since install. If I run the mill at 3000 RPM I can feel the spindle warming up after about 20 minutes, but the spindle still rotates freely so isn't "tightening up" thus indicating too much preload. It's great not to have to think about greasing those bearings. Great investment.
