SKF 3304 A-2Z C3 Double Row Ball Bearing Back to Back Arrangement 20 mm Bore With Sheet Metal Cage and C3 Internal Clearance for High Load Performance in Industrial Machinery

SKF 3304 A-2Z/C3 Double-Row Ball Bearing for 20 mm bore
✔️ Single bearing, 20 mm bore, shields both sides, C3 clearance

SKF 3304 A-2Z/C3 is a two-row angular contact ball bearing built to handle substantial radial loads in industrial equipment. It features shields on both sides and a non-contact seal to minimize friction, with a 30° contact angle and C3 internal clearance. Typical uses include conveyors, gearboxes, and motor-driven assemblies where shaft alignment matters and long life is a must.

✅ Double-row angular contact design back-to-back for high radial load capacity
✅ Bore 20 mm (0.79 in); outer diameter 50.8 mm (2.00 in); width 22.2 mm (0.87 in)
✅ Shielded on both sides; non-contact seal reduces friction and wear
✅ Basic dynamic load rating 24.5 kN; static rating 15.6 kN
✅ Grease lubrication; SKF Explorer class; C3 internal clearance
