SKF - 71905 CE/HCP4AQGA

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. Applications : Infrastructure and Construction, Robotics and Automation, Aerospace Components, Machine Tool Spindles. CE= 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, L= Annular Groove With Two Lubrication Holes And Two Annular Grooves Fitted With O-Rings In The Outer Ring (Optimized Position) For Direct Oil Lubrication, QGA= Quad Set, Single Row Angular Contact Ball Bearing For Universal Matching. Two Bearings Arranged Back-To-Back Or Face-To-Face Will Have A Light Preload.
