SKF 3309A-2RS1 — Double-row angular contact ball bearing
SKF · Bearings & Power Transmission · Double-Row Angular Contact Bearings
SKF 3309A-2RS1 double-row angular contact ball bearing. Double-row angular contact ball bearing (32xx-2Z, 33xx, 52xx / 53xx) taking heavy combined radial and axial load in both directions from a single position. Contact angle 30° or 45°. Standard shielded (2Z) or contact-sealed (2RS1) execution. Suitable for pump impeller shafts, gearbox output shafts, propeller-shaft thrust ends on smaller marine gearboxes. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options (material, sealing, cage, precision, clearance, lubricant). Genuine SKF supply carries the SKF logo etch or moulded mark and hologram-authenticated packaging.
