SF626 Bearing Product Overview & Core Advantages
The SF626 is a metric single row deep groove ball bearing engineered for precision radial load applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance and durability. Its compact design, featuring a 6 mm bore and 19 mm outer diameter, makes it ideal for space-constrained assemblies requiring high reliability. The bearing is designed to operate efficiently within a wide temperature range of -30° to 110 °C and complies with RoHS and REACH standards, ensuring material safety and environmental responsibility.
SF626 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF626 | Standard model designation for a single row deep groove ball bearing with a 6 mm bore. |
| Open (Seal Type) | The bearing is unsealed, allowing for custom lubrication and high-speed operation, but requiring a clean operating environment. |
| ABEC1 | Specifies the precision tolerance class, ensuring consistent running accuracy for general applications. |
| MC3 | Indicates the standard radial internal clearance group (0.002mm to 0.013mm), suitable for most operating conditions. |
SF626 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and optimized stainless steel cage contribute to a high limiting speed of 28,800 rpm, making it suitable for demanding high-rotation applications.
- Robust Load Capacity: With a dynamic load rating of 402 lbf and a static load rating of 145 lbf, this deep groove ball bearing provides reliable performance under significant radial loads.
- Corrosion Resistance: The all-stainless steel construction ensures long-term performance in humid or corrosive environments, enhancing bearing lifespan.
- Precision Engineering: Manufactured to ABEC1 tolerance standards with controlled internal clearance, it delivers smooth, low-vibration, and precise operation.
SF626 Bearing Typical Application Areas
This bearing is widely used in applications requiring small bore sizes, high speed, and corrosion resistance. Key industries and equipment include:
- Precision Instruments: Optical encoders, small motors, and medical devices.
- Electric Motors: Small fans, miniature pumps, and servo motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Food Processing and Packaging Machinery: Where corrosion resistance and cleanability are paramount.
