SF63804 Bearing Product Overview & Core Advantages
The SF63804 is a metric stainless steel flanged ball bearing engineered for precision radial load applications requiring corrosion resistance and compact design. As a single row ball bearing with an integrated flange, it offers simplified mounting and precise axial location. Constructed entirely from stainless steel components, it provides excellent durability in demanding environments. Its open seal type allows for easy re-lubrication, making it a versatile and reliable choice for a wide range of industrial applications.
SF63804 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF63804 | Basic bearing designation indicating a flanged, deep groove ball bearing with specific dimensions. |
| Open | No integral seals or shields. This allows for higher limiting speeds and custom lubrication but requires a clean operating environment or external sealing. |
| ABEC-1 | Specifies the tolerance class, indicating standard precision suitable for most general industrial applications. |
| C0 | Denotes the standard radial internal clearance group (0.002mm to 0.013mm) for normal operating conditions. |
SF63804 Bearing Structural Features & Performance Benefits
- Integrated Flange for Easy Mounting: The flange (OD: 35mm, Thickness: 2mm) provides a positive locating surface, simplifying assembly and ensuring accurate axial positioning without additional components.
- High Corrosion Resistance: The stainless steel ring material and 300 series stainless steel shield material offer superior protection against rust and corrosion, ideal for washdown environments or applications exposed to moisture.
- Robust Load Capacity: With a radial dynamic load rating of 812 lbf and a static load rating of 498 lbf, this bearing is designed to handle significant radial forces in compact spaces.
- Optimized High-Speed Performance: The stainless steel cage and open design contribute to a high limiting speed of 18,900 rpm, making it suitable for high-rotation applications.
- Wide Operating Temperature: A functional range from -30°C to 110°C ensures reliable performance in varied thermal conditions.
SF63804 Bearing Typical Application Areas
- Food & Beverage Processing Equipment: Conveyors, mixers, and fillers where corrosion resistance and washdown are critical.
- Medical and Laboratory Devices: Small pumps, analyzers, and instrumentation requiring precise, reliable rotation.
- Office Automation Equipment: Printers, scanners, and copiers utilizing the bearing's compact flanged design and high-speed capability.
- Small Electric Motors and Gearboxes: Providing support for motor shafts in compact assemblies.
