SKF 6308-2RS1/C3 High-Performance Sealed Ball Bearing
The SKF 6308-2RS1/C3 is a robust and highly versatile single row deep groove ball bearing that engineers primarily select for demanding industrial environments. 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 6308-2RS1/C3 features very precise physical dimensions. It has a bore diameter of 40 mm, an outside diameter of 90 mm, and a width of 23 mm. Regarding its structural strength, the unit offers a basic dynamic load rating of 42.3 kN and a basic static load rating of 24 kN. Furthermore, it reaches a limiting speed of 5,000 r/min. Therefore, this model serves as an ideal choice for machinery where high capacity and sealing integrity remain critical factors for efficiency.
The Benefits of 2RS1 Sealing and C3 Clearance
Specifically, the “2RS1” designation indicates that the bearing features contact seals on both sides made of acrylonitrile-butadiene rubber. These seals effectively protect the internal mechanics from dust, water, and contaminants. Moreover, the C3 radial internal clearance provides extra room for thermal expansion during operation. Because the seals are contact-type, they provide superior protection compared to metal shields. As a result, the internal components stay protected and well-lubricated even when the machinery operates in dirty or damp environments.
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 0.63 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 6308-2RS1/C3 appears in many heavy-duty sectors. For example, electric motors, agricultural machinery, wash-down applications, and industrial gearboxes frequently rely on this specific model. Finally, the combination of high load capability and contact sealing ensures that your machinery operates with maximum precision. This makes it a top-tier selection for any project that prioritizes both high capacity and long-term durability.
