SKF 6306-2Z High-Performance Shielded Ball Bearing
The SKF 6306-2Z is a robust and highly versatile single row deep groove ball bearing that engineers primarily select for demanding industrial applications. Firstly, this model belongs to the prestigious SKF Explorer performance class. This designation ensures that the bearing provides higher load ratings and reduced friction, which leads to a significantly longer service life compared to standard industrial options. Consequently, users benefit from a durable component that performs reliably under heavy operational conditions.
Technical Dimensions and Exceptional Capacity
In addition to its optimized internal geometry, the 6306-2Z features very precise physical dimensions. It has a bore diameter of 30 mm, an outside diameter of 72 mm, and a width of 19 mm. Regarding its structural strength, the unit offers a basic dynamic load rating of 29.6 kN and a basic static load rating of 16 kN. Furthermore, it reaches a powerful reference speed of 20,000 r/min and a limiting speed of 11,000 r/min. Therefore, this model serves as an ideal choice for machinery where high capacity and rotational speed remain critical factors for efficiency.
Key Features and 2Z Metal Shielding
Specifically, the “2Z” designation indicates that the bearing features non-contact metal shields on both sides. These shields effectively protect the internal mechanics from dust and larger particles without creating additional friction. Because the shields are non-contact, the bearing can maintain much higher speeds than contact-sealed versions. Moreover, the use of premium bearing steel and a durable sheet metal cage ensures excellent structural stability during operation. As a result, the SKF 6306-2Z maintains its precision even during continuous, high-speed use.
Additionally, this bearing features a cylindrical bore type and standard radial internal clearance (CN). The design does not include filling slots or a locating feature on the outer ring, which keeps the total mass at a sturdy 0.353 kg. Because it comes pre-filled with high-quality grease, it requires very little maintenance throughout its functional lifecycle.
Common Industrial Applications
Because of its balanced performance and durable build, the SKF 6306-2Z appears in many heavy-duty sectors. For example, electric motors, large pumps, agricultural machinery, and industrial gearboxes frequently rely on this specific model. Finally, the combination of high-speed capability and protective shielding ensures that your machinery operates with maximum precision. This makes it a top-tier selection for any project that prioritizes both high load performance and long-term durability.
