SKF - 71912 CD/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. Material : Hybrid (Ceramic/Silicon Nitride balls with Steel rings). Features are : Very High Running Accuracy, Very High Load Carrying Capacity, Electrical Insulation, Extended Service Life, Axial Stiffness, Open Design, Vibration and Noise Reduction, Tight Tolerances, Temperature Tolerance, Reduced Maintenance. Applications : Machine Tool Spindles, Grinding Machines, Woodworking Machinery, Medical Equipment, Aerospace Industry, Robotics & Automation, Semiconductor Manufacturing. CD= 15° Contact Angle, 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, 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.
