SKF - 71900 ACE/P4A

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 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. Material : Uses ceramic (silicon nitride) balls, which are harder, lighter, and more durable than steel, reducing heat and allowing for higher speeds. Features are : Very High Running Accuracy, Accommodate Very High Speeds, Enhanced Service Life, Accommodate Relatively High Radial Loads And Large Unilateral Axial Loads, Reduced Centrifugal Force, Super-Precision Accuracy, Lower Maintenance. Applications : Grinding Machines, Woodworking Machinery, Semiconductor Industry, Aerospace Components, Medical & Laboratory Equipment, Semiconductor & Vacuum Environments. 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.
