SKF - 7020 ACE/HCP4AL1

Details

These super-precision, high-speed E design, single row angular contact ball bearings, with 25° contact angle, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They are designed to accommodate very high speeds. Compared to the equivalent SKF B design high-speed bearings, have a slightly higher speed capability and can accommodate heavier loads. They have two lubrication holes, an annular groove, and two annular O-ring grooves in their outer rings. Material : Hybrid construction featuring high-carbon chromium steel rings and ceramic (Silicon Nitride) balls. Features are : Very High Running Accuracy, Accommodate Very High Speeds, Suitable For Direct Oil-Air Lubrication, Accommodate Relatively High Radial Loads and Large Unilateral Axial Loads, 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, 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,  L1= Annular Groove With Two Lubrication Holes And Two Annular Grooves Fitted With O-Rings In The Outer Ring (Optimized Position) For Direct Oil Lubrication.
