SF6803 Bearing Product Overview & Core Advantages
The SF6803 is a metric miniature flanged ball bearing engineered for compact applications demanding high precision and reliable performance. Constructed as a single row bearing, it is optimized to handle primarily radial loads efficiently. Its defining feature is the integral flange, which simplifies mounting and provides accurate axial location within assemblies. Manufactured with corrosion-resistant stainless steel rings and shield, it is suitable for a wide operating temperature range, making it an ideal choice for applications where space is limited and reliability is critical.
SF6803 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF6803 | Standard model number for a metric, flanged, miniature deep groove ball bearing. |
| Open (Seal Type) | The bearing is unsealed, offering minimal torque for high-speed operation but requiring a clean environment or external sealing. |
| ABEC-1 | Specifies the precision class, indicating standard tolerances for runout and dimensional accuracy. |
| C0 | Denotes standard radial internal clearance (0.002mm to 0.013mm), suitable for most general applications. |
SF6803 Bearing Structural Features & Performance Benefits
Flanged Design: The integrated flange (Ø28 mm) ensures easy installation and precise axial positioning, reducing assembly complexity and cost.
High-Speed Capability: With a limiting speed of 21,600 rpm and an open design for minimal friction, this bearing is engineered for high-speed applications.
Corrosion Resistance: The use of stainless steel for the rings, cage, and shield provides excellent resistance to corrosion, extending service life in harsh or washdown environments.
Robust Load Capacity: Despite its compact bearing dimensions (17mm bore, 26mm OD, 5mm width), it offers a dynamic load rating of 451 lbf and a static load rating of 295 lbf for reliable performance under radial loads.
SF6803 Bearing Typical Application Areas
- Small Electric Motors and Fans
- Precision Instruments and Optical Encoders
- Office Automation Equipment (e.g., Printers, Scanners)
- Medical Devices and Dental Handpieces
- Radio-Controlled Models and Drones
