SF699 Bearing Product Overview & Core Advantages
The SF699 is a metric single row deep groove ball bearing designed for exceptional performance in compact applications. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers superior corrosion resistance. This bearing is optimized for radial load applications and operates effectively across a wide temperature range from -30°C to 110°C. Its compact dimensions (9mm bore, 20mm OD, 6mm width) combined with a flanged outer ring for secure mounting make it an ideal choice for applications demanding high reliability and space efficiency.

| Code Segment | Technical Meaning |
|---|---|
| SF699 | Basic bearing model number |
| Open (Seal Type) | No integral seals or shields, allowing for higher speeds and custom lubrication |
| MC3 | Specifies a radial internal clearance group of 0.002mm to 0.013mm |
| ABEC1 | Indicates standard precision class tolerance |
SF699 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The bearing rings, balls, and cage are manufactured from stainless steel, providing excellent resistance to corrosion and enabling use in harsh environments.
- Deep Groove Raceway: The geometry of the deep groove raceway is optimized for handling radial loads efficiently.
- Flanged Outer Ring: The integrated flange (23mm OD, 1.5mm thick) simplifies axial location and mounting, improving assembly accuracy and rigidity.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 30,600 rpm.
- Standard Internal Clearance (MC3): Provides optimal performance for a wide range of standard operating conditions and fits.
SF699 Bearing Typical Application Areas
This bearing is well-suited for applications requiring compact size, corrosion resistance, and reliable performance under radial loads. Key industries and equipment include:
- Small electric motors and precision instruments
- Medical and dental handpieces
- Food processing and packaging machinery
- Optical and encoder systems
- Various light-duty industrial machinery
