SKF - 71924 ACEGA/HCP4A

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, an annular groove, and two annular O-ring grooves in their outer rings. Features are : Very High Running Accuracy, Accommodate Very High Speeds, Suitable For Direct Oil-Air Lubrication, Universally Matchable, Maintenance-Free. Applications : Machine Tool Spindles, Aerospace & Defense, Medical & Laboratory Equipment, Semiconductor Manufacturing, Renewable Energy Systems. 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, L= Annular Groove With Two Lubrication Holes And Two Annular Grooves Fitted With O-Rings In The Outer Ring (Optimized Position) For Direct Oil Lubrication.
