There is at least one highly regarded low end CNC mill being sold today that uses ABEC3 bearings to mount the ballscrews. OTOH, if you want the best, ABEC 7 is the way to go. Note how small the actual differences are between these two grades: 0.00008″ runout vs 0.00003″ runout. Half a ten thouh!
Ball Mill Maintenance & Installation Procedure
The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill. When standing at the feed end of the mill, and facing the mill, if the mill rotates clockwise, it is a right hand mill.

I have a spare girth gear that (might) belongs to a ball mill, and I need to check it with the pinion, and perform contact test, backlash, radial and axial runout (2 sections), et cetera). There is a distinct possibility the pinion does not correspond to the gear for whatever reason (cough!, cheap, cough!).
ball mill girth gear installation pdf
The ball mill is driven through a girth gear at a speed of 16 rev min −1 and is mounted on the head wall of the ball mill. The girth gear, 6360.6 mm in diameter, is driven by two pinions, each being connected via a gear box and coupling to a 1560 kW electric motor. The speed ratio between the pinion and the girth gear is 7:1.
