Diamond Machining: Ultraprecision Machine Technology

This means that thermal growth is minimal and there is virtually no wear during spindle operation. Also, like hydrostatic oil-bearing slides, air-bearing spindles have a tremendous bearing-averaging effect. This means that spindle rotation, in addition to being virtually friction free, is extremely smooth.

Machining Center Spindles: What You Need to Know

The fit of the bearings on the spindle bearing journal is CRITICAL! A tight fit is acceptable, but a too loose fit or non-concentric spindle is a rejected lathe! Because these lathes are not made to high quality tolerances, the bearings are intentionally made too tight on the Spindle shaft journals. This prevents you from adjusting the Pre-Load.

Spindle (tool) - Wikipedia

In machine tools, a spindle is a rotating axis of the machine, which often has a shaft at its heart. The shaft itself is called a spindle, but also, in shop-floor practice, the word often is used metonymically to refer to the entire rotary unit, including not only the shaft itself, but its bearings and anything attached to it ( chuck, etc.).

The shorter spindle hubs are accomplished by moving the rear and front bearings closer together. The tradeoff is that the wheel hubs are a bit less supported for larger wagons and heavier loads than having a wider standard hub. You will need to use wheels with short spindle hubs on the short spindle axles and vice versa for the long spindle hubs.
