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. Material: High-quality bearing steel rings with ceramic (Si3N4) balls and a fabric-reinforced phenolic resin cage. Features are: Very High Running Accuracy, Very High Load Carrying Capacity, Suitable For Direct Oil-Air Lubrication, Universally Matchable, Relatively High Speed And Stiffness, Electrical Insulation. Application: Machine Tool Spindles, Medical and Dental Equipment, Aerospace and Defense, Semiconductor Manufacturing. 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 , P4A= Dimensional Accuracy In Accordance With ISO Tolerance Class 4, Running Accuracy Better Than ISO Tolerance Class 4, H1= Same As, W64F= W64-Solid Oil Filling And F (Food Compatible Grease, 62 cSt at 40°C 10.1 cSt at 100°C).
