SKF Single Row Deep Groove Ball Bearing 30 mm ID, 72 mm OD, 19 mm Width, Cylindrical Bore, Sheet Metal Cage, Steel 6306/C4

SKF 6306/C4 single row deep groove ball bearing features a 30 mm inside diameter, 72 mm outside diameter, and 19 mm race width designed for reliable rotational support in various industrial applications. This bearing type supports both radial loads and moderate axial forces, making it ideal for high-speed rotating equipment in electric motors, precision gearboxes, and automation systems.

The cylindrical bore requires housings or adaptors to provide an interference or locating fit suitable for a plain bore installation. The open ends allow unobstructed lubrication, facilitating easy direct lubricant application and re-lubrication intervals. However, external sealing is recommended if contamination protection is necessary.

The bearing includes a sheet metal cage offering low mass while securely retaining the balls. Its plain steel raceways ensure consistent contact geometry and excellent wear resistance, contributing to longevity and reliable performance. The internal C4 clearance reduces thermal preload during high-temperature operation, while the limiting speed capability of 13,000 rpm supports high-speed shaft rotation demands.

With a static load rating of 16 kN, the bearing minimizes permanent deformation under peak loads, and the dynamic load rating of 29.6 kN provides enhanced operational load handling. Suitable applications include electric motor spindle support in industrial drives, precision gearbox radial support in automation, rotary encoders for electronics, rotor shafts in small fans and blowers, and pump shafts where open-end lubrication access is desirable.

Material considerations include steel races and balls, so corrosion resistance depends on lubrication choice or additional protective measures in corrosive environments. Supports radial loads and moderate axial forces efficiently.
