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. They have two lubrication holes in their outer rings. Materials: High-quality carbon chromium bearing steel for rings and balls, with a lightweight, high-performance fiber-reinforced phenolic resin cage. Features are: Suitable For Direct Oil-Air Lubrication, Very High Running Accuracy, Very High Load Carrying Capacity, Relatively High Speed and Stiffness, Optimized Power Density. Applications: Heavy-Duty Machining & Tooling, High-Precision Industrial Equipment, Semiconductor Wafer Handling, Optical Tracking Systems, Advanced Engineering & Robotics, Power Generation, Precision Ball Screw Supports. CD= 15° Contact Angle, P4A= Dimensional Accuracy In Accordance With ISO Tolerance Class 4, Running Accuracy Better Than ISO Tolerance Class 4, H=Two Lubrication Holes On The Non-Thrust Side Of The Outer Ring.
