More Information About Nachi & FAG Precision Bearings
Spindle bearings are a single row angular contact ball bearings, comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed designs.
Spindle bearings have restricted tolerances. They are particularly suitable for bearing arrangements with very high requirements for guidance accuracy and suitability for high speeds. They have proved extremely suitable for spindle bearing arrangements in machine tools.
FAG Precision Bearings
Standard spindle bearings B70, B719 and B72 have steel balls.
X-life ultra bearings have bearing rings made from corrosion-resistant steel that contains nitrogen and has a particularly fine structure (prefix X) and ceramic balls. They fulfil very high requirements for speed and load carrying capacity. The bearings have a longer life compared to conventional bearings. Most of the spindle bearings are available as X-life ultra bearings.
