Reducing costs is an important factor for most companies. The ability to use low-cost shafting heavily depends on the bearings chosen to run on it. For example, ball bearings require very hard (60HRC or above) and smooth (under 4rms) shafting. Bronze bearings are similar: the shafting must be harder than the bronze material being used.

Basically there is one bearing at the front of the spindle, and one at the rear. There is a preload cylinder between them, on the spindle itself, to space the inner races apart, and the outer races are separated by the headstock casting itself. The older hardinges had three bearings, there is an angular contact pair at the front,

A rolling-element bearing, also known as a rolling bearing,[1] is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding. One of the earliest and ...

Many people prefer to use self-aligning bearing flanges for the wheels like the one pictured here. If you bolt two of these to the wheel, that makes for a quick and easy way to mount the bearings. If you go that route, you should glue and bolt the bearings to the wheels very firmly. 150 pounds of tension on the blade is like 300 pounds of force ...

$300 seems pretty cheap to me. If I can put bearings in a spindle for $300, even for a hobby machine, you have $300 invested in the machine. They put a new bearing in the C axis of the mill I used to run. The bearing was $15000. We replaced it because it had .005mm run out. It's all perspective.
