SKF - 7216 CD/HCP4AQBCD

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. 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 And (E) Small Size Balls, HC= Bearing Or Bearing Components Of Ceramic, P4A= Dimensional Accuracy In Accordance With ISO Tolerance Class 4, Running Accuracy Better Than ISO Tolerance Class 4, QBCD= Four Matched Single Row Deep Groove Or Angular Contact Ball Bearings Arranged Tandem - Back-To-Back, Zero Preload.
