SKF - 7012 ACBGA/HCP4AL

Details

These super-precision, high-speed, single row angular contact ball bearings with 15° or 25° contact angle accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. Compared to the equivalent SKF E design high-speed bearings, these are suited for lighter 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, an annular groove, and two annular O-ring grooves in their outer rings. Features are: Suitable For Direct Oil-Air Lubrication, Very High Running Accuracy and Speeds, Reduced Stresses on Rolling Contact Surfaces, Universally Matchable. Applications : Machine Tool Spindles, Semiconductor Manufacturing, Medical Equipment. ACB= 25° Contact Angle, High-Speed B Design, 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 For Direct Oil Lubrication.
