NACHI - 7903ACYU/GLP4

Details

These bearing is a super-precision, single-row angular contact ball bearing engineered for high-performance applications, such as machine tool spindles, that require extreme rotational accuracy and high-speed stability. This bearing is designed to handle combined radial and axial loads. Material : High carbon chromium bearing steel with a resin (polyamide) retainer to minimize friction and heat at high velocities. Feeatures are : Minimal Vibration, Low Heat Generation, Higher Axial Rigidity, Stable Support, Maintenance and Longevity, Super-Precision Accuracy. Applications : CNC Equipment, Milling & Grinding, Robotics & Automation, Aerospace & Defense, Medical & Scientific Equipment, Semiconductor Manufacturing, Textiles & Printing. AC=25° Contact Angle, Y=Polyamide Cage, U=Angular Contact Single Bearing - Ground For Universal Duplexing, GL=Light Preload, P4=Dimensional & Running Accuracy To Iso Tolerance Class 4 (More Accurate Than P5)-ABEC.7.
