SKF - 7018 CD/HCP4ATBTA

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, 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, TBTA= Set Of Three Matched Single Row Deep Groove Or Angular Contact Ball Bearings, Light Preload.
