        Overview

        FAG 3311 Angular Contact Ball Bearing supports combined radial and one-direction axial load through a defined contact angle. It is a high-speed, high-precision choice for pumps, compressors, machine tools, and spindle-related positions where axial rigidity and rotational accuracy matter.

        The inner and outer ring raceways are offset to create a contact angle. Single-row, double-row, or matched arrangements can be used to meet axial load direction, preload, and rigidity requirements.

        Key features

        • ·Supports combined radial and one-direction axial load
        • ·High-speed and high-accuracy operation
        • ·Preload and rigidity adjustable through matched mounting
        • ·Suitable for precision rotating assemblies

        Typical applications

        • ·Machine tool spindles and support shafts
        • ·Pumps and compressors
        • ·High-speed motors
        • ·Precision gearboxes and robot drives

        Selection guidance

        Select by contact angle, arrangement, preload, precision class, axial load direction, and operating speed.
