SKF - 7008 ACD/P4AQGC

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 Load Carrying Capacity, Enhanced Lubrication. Applications : Robotics and Automation, Aerospace Components, Machine Tool Spindles. ACD= 25° Contact Angle, P4A= Dimensional Accuracy In Accordance With ISO Tolerance Class 4, Running Accuracy Better Than ISO Tolerance Class 4, QGC= Set Of Four Bearings For Universal Matching, Heavy Preload.
