Construction: Double-row rolling elements; inner and outer rings with dual raceways; fixed contact angle; available in three mounting configurations: back-to-back, face-to-face and in series. Performance: Capable of withstanding radial loads and bidirectional axial loads; superior rigidity and anti-tipping capacity compared to single-row angular contact ball bearings. Applications: High-rigidity, high-precision, heavy-load conditions, such as machine tool spindles, precision gearboxes and high-power motors. Advantages: A single bearing can replace a combination of two single-row bearings, simplifying installation and saving space.
