SKF SKF 619/6-2Z High-Performance Thin Section Ball Bearing
The SKF 619/6-2ZÂ is a high-precision thin section deep groove ball bearing that engineers primarily select for applications with extremely tight space constraints. Firstly, this bearing offers an incredibly compact design while maintaining the high rotational accuracy expected from SKF. It belongs to the single-row deep groove category, which provides reliable performance for lightweight and high-speed industrial components.
Technical Dimensions and High-Speed Performance
In addition to its space-saving geometry, the 619-6-2Z features very specific and delicate dimensions. It has a bore diameter of 6 mm, an outside diameter of 15 mm, and a width of 5 mm. Regarding its performance capabilities, the bearing supports a basic dynamic load rating of 0.884 kN and a basic static load rating of 0.27 kN. Furthermore, it reaches an impressive reference speed of 100,000 r/min and a limiting speed of 50,000 r/min. Therefore, this model serves as an excellent choice for high-speed machinery where weight and size remain critical factors.
Key Features and Shielded Protection
Specifically, the “2Z” designation indicates that the bearing features metal shields on both sides. These non-contact shields protect the internal grease and components from dust and environmental contamination without increasing friction. Because it utilizes high-quality bearing steel, the unit maintains excellent structural integrity even at maximum rotational speeds. Moreover, the cylindrical bore type and standard radial internal clearance (CN) ensure a stable and predictable fit for precision shafts.
Additionally, this bearing does not include filling slots or a locating feature on the outer ring. This streamlined “Thin Section” geometry reduces the overall mass of the component to just 0.0037 kg. As a result, the design significantly lowers rotational inertia, which allows your equipment to accelerate and decelerate more efficiently.
Common Industrial Applications
Because of its unique size and shielded design, the SKF 619-6-2Z is essential in specialized sectors. For example, medical instruments, miniature motors, robotics, and high-end office equipment frequently rely on this specific thin-section model. Finally, the pre-greased shielded configuration supports smooth, maintenance-free movement in clean environments. This makes it a top-tier selection for engineers who prioritize both precision and long-term reliability.
