SKF - S71909 ACD/P4A

Details

These super-precision, high-capacity, single row angular contact ball bearings, with 25° contact angle, with seals, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They are designed to accommodate heavy loads at relatively high speeds under low to moderate operating temperatures. Material: Incorporates ceramic (silicon nitride) balls which are lighter and harder than steel, further enhancing speed capability and extending service life. Features are: Very High Running Accuracy, Very High Load Carrying Capacity, Relatively High Speed And Stiffness, Non-Contact Seals, Integral Sealing Prolongs Bearing Service Life. Applications: Machine Tool Spindles, Medical and Dental Equipment, Aerospace and Defense, Semiconductor Manufacturing. S= Sealed On Both Sides With Non-Contact Seals, ACD= 25° Contact Angle And (E) Small Size Balls, P4A= Dimensional Accuracy In Accordance With ISO Tolerance Class 4, Running Accuracy Better Than ISO Tolerance Class 4.
