Double-sealed double-row self-aligning ball bearings feature a spherical raceway on the outer ring, providing self-aligning capability. Fitted with seals on both sides, they effectively prevent the ingress of dust and moisture. These bearings are primarily designed to carry radial loads, whilst also being capable of withstanding minor axial loads in both directions. With their compact design and low maintenance requirements, they are commonly used in applications such as textile machinery, conveying equipment, fans and agricultural machinery.
