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.

This type of bearing is used for appliions requiring high running accuracy and tight dimensional tolerances. Use of nonmetallic retainers such as phenolic can help to achieve higher speeds. View
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
Air Spindles and Rotary Stages - New Way Air Bearings
Apr 04, 2013· New Way Air Spindles are an exceptionally low flow technology, taking almost six hours to push one cubic meter of air through a 50mm x 100mm bearing, and thus, are extremely efficient in operation when compared to orifice-based systems.If airflow is somehow disrupted to the air bearing, the porous nature of the bearing surface means depressurization will occur …
7. Lubriion of Bearings
