SKF - 71914 ACE/P4ATGA | Angular Contact Ball bearing Spindle | 70 × 100 × 48 mm

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. Material: High-carbon chromium bearing steel rings and balls with a lightweight fabric-reinforced phenolic resin (hard fiber) cage to reduce centrifugal forces. Features are : Very High Running Accuracy, Accommodate Very High Speeds, High Axial and Radial Stiffness, Maintenance-Free, Precision & Stability, Low-Friction Grease. Applications : Machine Tool Spindles, Grinding Machines, Aerospace & Defense, Medical & Laboratory Equipment, Semiconductor Manufacturing, Robotics & Automation, Renewable Energy Systems, Marine & Underwater Technology. ACE= 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, TG= Three Bearings For Universal Matching, A= Light Preload.
