F6809 Bearing Product Overview & Core Advantages
The F6809 is a metric single row flanged ball bearing engineered for compact radial load applications requiring precise positioning. Featuring a stainless steel cage and chrome steel components, it delivers reliable performance with ABEC-1 precision tolerance. The integrated flange facilitates secure mounting and alignment, making it ideal for space-constrained assemblies where high rotational accuracy and rigid support are critical. Its open design allows for customized lubrication strategies to match specific operational requirements.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| F | Flanged outer ring design for simplified mounting and alignment |
| 6809 | Standard bearing series designation indicating 45mm bore diameter and 58mm outer diameter |
| Open | No seals or shields, allowing for custom lubrication and high-speed operation |

F6809 Bearing Structural Features & Performance Benefits
Flanged Construction: The integrated flange (61mm OD, 1.5mm thickness) provides secure mounting and eliminates the need for additional housing components, reducing assembly complexity and cost.
High-Precision Components: Manufactured with chrome steel rings and 3.969mm diameter balls arranged in a 21-ball configuration, ensuring smooth operation and consistent radial load distribution.
Optimized Cage Design: The stainless steel cage maintains ball spacing at high rotational speeds up to 11,000 rpm, enhancing operational stability and service life.
Precision Tolerance: ABEC-1 tolerance class with strict dimensional controls (bore: -0.012mm to 0, OD: -0.013mm to 0) ensures reliable fitment and minimal runout in precision applications.
