F6906ZZ Bearing Product Overview & Core Advantages
The F6906ZZ is a single row flanged ball bearing designed for compact applications requiring precise radial positioning. Featuring integral stainless steel shields (ZZ) on both sides, this metric bearing offers reliable contamination protection while maintaining low friction operation. Its flanged design provides simplified mounting and axial location, making it ideal for applications where housing machining costs need minimization. The bearing delivers consistent performance across a wide temperature range (-30° to 110°C) and comes pre-lubricated for immediate installation.

F6906ZZ Bearing Structural Features & Performance Benefits
Compact Flanged Design: The integrated flange (50 mm OD, 2 mm thickness) enables straightforward mounting and eliminates the need for complex housing shoulders, reducing assembly time and cost while providing reliable axial positioning.
Shielded Protection: Double 300 series stainless steel shields effectively retain lubricant and exclude contaminants, extending bearing service life in demanding environments without significant speed reduction.
Precision Engineering: Manufactured to ABEC-1 tolerance class with C0 radial clearance (0.002-0.013 mm), ensuring smooth operation and consistent performance in precision applications.
Optimized Load Capacity: With a dynamic load rating of 1628 lbf and static load rating of 1126 lbf, the bearing handles substantial radial loads despite its compact dimensions (47 mm OD × 9 mm width).
High-Speed Capability: The stainless steel cage and optimized ball complement (14 balls of 4.762 mm diameter) enable operation up to 14,000 rpm, suitable for various high-speed applications.
