These super-precision, high-capacity, single row angular contact ball bearings, with 15° contact angle, 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. Material : It is made from ultra-clean 100Cr6 high-carbon chromium steel paired with a lightweight, oil-absorbing phenolic resin cage. Features are: Very High Running Accuracy, Relatively High Speed and Stiffness, High Load Carrying Capacity, Strict Noise and Vibration Control, Low Heat Generation, Optimized Raceway Geometry. Applications: Milling & Boring Machines, Precision Engineering & Specialised Machinery, Semiconductor Industry, Grinding Machines. CD= 15° Contact Angle, P4A= Dimensional Accuracy In Accordance With ISO Tolerance Class 4.
