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 Bearings | KRW Leipzig

Spindle bearings are a special type of single row angular contact ball bearings. They can absorb radial forces as well as axial and coined forces and are suitable for highest requirements of guiding and running accuracy, rigidity, increase in speed and decrease in friction due to their very limited tolerances.
