Features of Spindle bearings
Spindle bearings are 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.
Radial and axial load capacity
The bearings can support axial forces in one direction as well as radial forces. Spindle bearings used in an O or X arrangement can support axial forces in both directions and moments. Bearings in a tandem arrangement can only support axial loads in one direction.Spindle bearings are available with a contact angle a = 15° (suffix C) or a = 25° (suffix E).
life ultra bearings
X-X-life ultra bearings have bearing rings made from a 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 longer life compared to conventional bearings. Most series of spindle bearings are available as X-life ultra bearings.For a more detailed description, see Catalogue AC 41 130 Super Precision Bearings.
Operating temperature
The bearings are suitable for operating temperatures from –30 °C to +100 °C, restricted by the seal and cage material.The operating temperature must be taken into consideration when selecting the lubricant.
