Machine Tool Spindle Bearing Lubriion: What To Know

Spindle bearings must be properly lubried to maintain a film of lubricant between the rolling elements and the bearing raceways. Without lubriion, the rolling elements will have direct contact with the raceways, and this will result in heat, race deterioration, rolling element deterioration, cage disintegration, and ultimately bearing/spindle failure.

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
