SKF 6208-2Z/C3 High-Performance Shielded Ball Bearing
The SKF 6208-2Z/C3 is a highly versatile single row deep groove ball bearing that engineers primarily specify 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 robust component that performs reliably under continuous operational conditions.
Technical Dimensions and Exceptional Capacity
In addition to its optimized internal geometry, the 6208-2Z/C3 features very precise physical dimensions. It has a bore diameter of 40 mm, an outside diameter of 80 mm, and a width of 18 mm. Regarding its structural strength, the unit offers a basic dynamic load rating of 32.5 kN and a basic static load rating of 19 kN. Furthermore, it reaches a powerful reference speed of 18,000 r/min and a limiting speed of 9,000 r/min. Therefore, this model serves as an ideal choice for machinery where high capacity and rotational speed remain critical factors for efficiency.
The Benefits of 2Z Shielding and C3 Clearance
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. Moreover, the C3 radial internal clearance provides extra room for thermal expansion during operation. Because the shields are non-contact, the bearing can maintain much higher speeds than contact-sealed versions. As a result, the internal components stay protected and well-lubricated even when the bearing generates heat during heavy use.
Additionally, this bearing features a cylindrical bore type and a durable sheet metal cage. The design does not include filling slots or a locating feature on the outer ring, which keeps the total mass at a sturdy 0.371 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 6208-2Z/C3 appears in many heavy-duty sectors. For example, electric motors, conveyors, agricultural machinery, and industrial fans 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 performance and long-term durability.
