SKF 7010 CD/P4AQBCB Matched set of four super precision angular contact ball bearing

These sets of four 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", "tandem back-to-back, tandem face-to-face", "back-to-back and tandem", "face-to-face and tandem". Sets of four bearings arranged in tandem need to be mounted against a single bearing, or a set of bearings in tandem, to achieve the desired preload. All the other arrangements are available in different preload classes and correct mounting results in preload within a predetermined range, without the need for shims or similar devices. 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.
