SKF - 7018 ACD/HCP4ATBTC

Details

These sets of three matched super-precision angular contact ball bearings are available as universally matchable bearings or as preconfigured arrangements. Sets arranged in back-to-back and tandem, or face-to-face and tandem, are available in different preload classes and correct mounting results in preload within a predetermined range, without the need for shims or similar devices. Sets of three bearings paired in tandem need to be mounted against a single bearing, or another set of bearings in tandem, to achieve the desired preload. 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, Very High Load Carrying Capacity, High Axial and Radial Stiffness, 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. ACD= 25° 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, TBTC= Set Of Three Matched Single Row Deep Groove Or Angular Contact Ball Bearings, Heavy Preload.
