- Super-precision bearings
These sets of three matched super-precision angular contact ball bearings are available in a wide selection of designs, variants and arrangements, enabling them to be incorporated into virtually every machine tool application as well as other applications where precision bearings are required. Preconfigured arrangements include: "tandem", "back-to-back and tandem", "face-to-face and tandem". Sets arranged in back-to-back and tandem, or face-to-face and tandem, are available in different preload classes and correct mounting results in preload within a predetermined range, without the need for shims or similar devices. Sets of three bearings paired in tandem need to be mounted against a single bearing, or another set of bearings in tandem, to achieve a the desired preload. The bore and outside diameters of the bearings are matched to within a maximum of one-third of the permitted diameter tolerance, to provide better load distribution than single universally matchable bearings.
Benefits
- Very high running accuracy
- High axial and radial stiffness
- High axial and radial load carrying capacity
- Number of designs and variants available to suit the needs of a very large number of applications
