SKF - 71811 CDGB/P4

Details

These super-precision, high-capacity, single row angular contact ball bearings 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. 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. Material: High-quality bearing steel rings with ceramic (Si3N4) balls and a fabric-reinforced phenolic resin cage. Features are: Very High Running Accuracy, Very High Load Carrying Capacity, Relatively High Speed And Stiffness, Universally Matchable, Electrical Insulation. Application: Machine Tool Spindles, Medical and Dental Equipment, Aerospace and Defense, Semiconductor Manufacturing. CD= 15° Contact Angle, GB= Bearing For Paired Mounting In Random Order When Arranged Back-To-Back Or Face-To-Face There Will Be A Moderate Preload, P4A= Dimensional Accuracy In Accordance With ISO Tolerance Class 4, Running Accuracy Better Than ISO Tolerance Class 4.
