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.).. A machine tool may have several spindles, such as

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.
Axle Spindles - Repair VS. Replace - CT Axle & Spindle Repair
Aug 27, 2018· Other times the spindle is obviously damaged due the bearing burning up and hub falling on the axleshaft which rides on the spindle. This causes the end to wear thin and split beyond repair. Worst case is the hub and wheels leave the vehicle and the spindle hits the ground causing it to bend. In these cases the whole spindle needs to be replaced.
