SF6808ZZ Bearing Product Overview & Core Advantages
The SF6808ZZ is a metric flanged ball bearing engineered for precision applications requiring compact design and reliable performance. This single row bearing features a shielded design that provides effective protection against contamination while maintaining low friction. Manufactured with stainless steel rings and cage, it offers excellent corrosion resistance, making it suitable for demanding environments. Its primary advantage lies in its ability to handle radial loads efficiently while the integrated flange ensures secure mounting and precise axial location. With an ABEC-1 precision class and consistent performance, it delivers the high reliability expected in industrial and precision mechanical systems.

SF6808ZZ Bearing Structural Features & Performance Benefits
Compact Flanged Design: The integrated flange (55mm OD, 1.5mm thickness) allows for space-saving installation and eliminates the need for separate mounting components, reducing assembly time and cost.
Shielded Protection: Double stainless steel shields (ZZ designation) effectively retain lubrication and exclude contaminants, enhancing bearing service life in dusty or dirty environments.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with C0 radial clearance (0.002-0.013mm), ensuring smooth operation and consistent performance in precision applications.
Corrosion Resistance: Constructed with stainless steel rings and cage, providing excellent resistance to corrosion in humid or chemically aggressive environments.
Load Capacity: With a dynamic load rating of 996 lbf and static load rating of 845 lbf, this bearing delivers reliable performance under significant radial loads.
SF6808ZZ Bearing Typical Application Areas
- Small Precision Motors: Ideal for miniature DC motors and stepper motors requiring compact dimensions and reliable performance
