SKF - 71817 CD/P4QBCA

Details

These sets of four matched super-precision angular contact ball bearings are available as universally matchable bearings or in preconfigured arrangements. 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. Material : Constructed from high-quality bearing steel with a one-piece inner and outer ring and a plastic cage. Features are: Very High Running Accuracy, High Axial And Radial Stiffness, High Axial And Radial Load Carrying Capacity, Internal Design. Applications: Milling & Boring Machines, Precision Engineering & Specialised Machinery, Semiconductor Industry, Grinding Machines. CD= 15° Contact Angle, P4= Dimensional & Running Accuracy To ISO Tolerance Class 4 (More Accurate Than P5)-Abec.7, QBC= Four Matched Single Row Deep Groove Or Angular Contact Ball Bearings Arranged Tandem Back-To-Back, A= Light Preload.
