SF6908 Bearing Structural Features & Performance Benefits
Flanged Design: The integrated flange (65mm OD, 2.5mm thickness) enables easy mounting and precise axial positioning, eliminating the need for additional housing components and reducing assembly time.
High-Quality Materials: Stainless steel rings and cage provide excellent corrosion resistance, while chrome steel balls (6.747mm diameter, 14 pieces) ensure high load capacity and durability in demanding environments.
Optimized Performance: The single row construction with C0 radial clearance delivers stable operation across a wide temperature range (-30° to 110°C). The limiting speed of 9,900 rpm makes it suitable for various industrial applications.
Load Capacity: With a radial dynamic load rating of 277 lbf and static load rating of 2017 lbf, this bearing provides reliable performance under significant radial loads.
