SF6800 Bearing Product Overview & Core Advantages
The SF6800 is a metric miniature flanged ball bearing designed for compact applications requiring high precision and reliable performance. As a single row radial ball bearing with an integral flange, it offers excellent radial load capacity and simplified mounting and axial location. Manufactured with stainless steel rings and cage, it provides superior corrosion resistance, making it ideal for applications demanding longevity and consistent operation in various environments. Its compact dimensions and ABEC-1 precision class ensure smooth running and high reliability in demanding miniature assemblies.
SF6800 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF6800 | Standard model designation for this specific flanged miniature bearing series with a 10mm bore. |
| Open (Seal Type) | The bearing is unsealed (open), allowing for custom lubrication schemes but requiring a clean operating environment. |
| C0 (Radial Clearance) | Specifies a normal radial internal clearance group, suitable for most general applications. |
| ABEC-1 | Denotes the tolerance class, indicating standard precision manufacturing for smooth operation. |
SF6800 Bearing Structural Features & Performance Benefits
- Flanged Design for Easy Installation and Positioning: The integral flange (21mm OD, 1mm thickness) simplifies axial location within a housing, reducing assembly time and cost while improving positional accuracy.
- High-Capacity Miniature Construction: Despite its compact bearing dimensions (10mm bore, 19mm OD, 5mm width), it utilizes 10 precision balls (2.381mm diameter) to deliver a robust radial dynamic load rating of 348 lbf and a radial static load rating of 170 lbf.
- Corrosion-Resistant Materials: The use of stainless steel for the rings, cage, and shield ensures excellent resistance to corrosion, which is critical for longevity in humid or chemically aggressive environments.
- High-Speed Capability: With a limiting speed of 30,600 rpm, this bearing is engineered for high-speed applications in miniature machinery and precision instruments.
- Wide Operating Temperature Range: The specified temperature range of -30°C to 110°C ensures reliable performance across a broad spectrum of operating conditions.
