CNC4YOU MM32L spindle bearings.

Angular contact bearings are the most common bearings in spindles.

You might get away with repacking the bearings, however if they've been heated too much, then they may need replacing.

That's interesting as most of the teardown videos I have watched on Chinese spindles of machines like the Precision Mathews PM30 etc all have had taper roller bearings.

Obviously spindles that are designed to run at higher RPM would have angular contact bearings but most of the manual mill spindles I have seen have taper roller.
