SKF - 7020 ACEGA/HCP4AH1

Details

These super-precision, high-speed, E design, 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 for high-speed operation and, compared to SKF B design high-speed bearings, have a slightly higher speed capability and can accommodate heavier loads. 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. They have two lubrication holes in their outer rings. Features are : Very High Running Accuracy, Suitable For Direct Oil-Air Lubrication, Accommodate Very High Speeds, Universally matchable, Reduced Vibration, Enhanced Service Life, 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, GA= Single Row Angular Contact Ball Bearing For Universal Matching. Two Bearings Arranged Back-To-Back Or Face-To-Face Will Have A Light Preload, 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, H1=Two Lubrication Holes On The Thrust Side Of The Outer Ring.
