SKF - 7009 ACBGA/P4A

Details

These super-precision, high-speed, single row angular contact ball bearings with 15° or 25° contact angle accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. Compared to the equivalent SKF E design high-speed bearings, these are suited for lighter loads. Being universally matchable, they can be used together in arrangements to provide effective load sharing, within a predetermined preload range, without the use of shims or similar devices. Features are: Very High Running Accuracy, Accommodate High Speeds, Reduced Stresses on Rolling Contact Surfaces, Universally Matchable, Low Heat Generation, Rigidity and Stability, Reduced Friction Torque, Low Vibration Levels. Applications : Machine Tool Spindles, Pumps and Compressors, Semiconductor Manufacturing, Printing Machinery, Aerospace and Defense, Medical and Dental Equipment. ACB= 25° Contact Angle, High-Speed B Design, GA= Single Row Angular Contact Ball Bearing For Universal Matching. Two Bearings Arranged Back-To-Back Or Face-To-Face Will Have A Light Preload, P4A= Dimensional Accuracy In Accordance With ISO Tolerance Class 4, Running Accuracy Better Than ISO Tolerance Class 4.
