SKF 6204-2Z High-Performance Shielded Ball Bearing
The SKF 6204-2Z is a highly versatile single row deep groove ball bearing that engineers primarily specify for a wide range of industrial and commercial 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 demanding conditions.
Technical Dimensions and Exceptional Speed
In addition to its optimized internal geometry, the 6204-2Z features very precise physical dimensions. It has a bore diameter of 20 mm, an outside diameter of 47 mm, and a width of 14 mm. Regarding its performance capabilities, the bearing supports a basic dynamic load rating of 13.5 kN and a basic static load rating of 6.55 kN. Furthermore, it reaches an extraordinary reference speed of 32,000 r/min and a limiting speed of 17,000 r/min. Therefore, this model serves as an ideal choice for high-speed machinery where reliability and efficiency remain critical factors.
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 sealed versions. Moreover, the use of premium bearing steel and a durable sheet metal cage ensures excellent structural stability. As a result, the SKF 6204-2Z maintains its precision even during continuous, high-speed operation.
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 assembly process simple and straightforward. Because it comes pre-filled with high-quality grease, it requires very little maintenance throughout its lifecycle.
Common Industrial Applications
Because of its balanced performance and durable build, the SKF 6204-2Z appears in many demanding sectors. For example, electric motors, household appliances, agricultural machinery, and power tools 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.
