SKF - 7019 CDGA/HCP4AL

Details

These super-precision, high-capacity, 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 heavy loads at relatively high speeds under low to moderate operating temperatures. 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. Material : High-quality bearing steel rings with ceramic (Si3N4) balls and a fabric-reinforced phenolic resin cage. Features are: Very High Running Accuracy, Suitable For Direct Oil-Air Lubrication, Very High Load Carrying Capacity, Relatively High Speed And Stiffness, Universally Matchable, Electrical Insulation. Application: Machine Tool Spindles, Medical and Dental Equipment, Aerospace and Defense, Semiconductor Manufacturing. CD= 15° Contact Angle, 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.
