SF625 Bearing Product Overview & Core Advantages
The SF625 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. This bearing is characterized by its compact design with a 5 mm bore and 16 mm outside diameter, making it ideal for applications demanding high rotational accuracy and reliable performance in various environments. Its ABEC1 tolerance class ensures consistent operation, suitable for a wide temperature range from -30° to 110 °C.
SF625 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| SF625 | Standard designation for this specific bearing size (5mm bore, 16mm OD, 5mm width). |
| Open (Seal Type) | No integral seals or shields, allowing for higher limiting speed and requiring external lubrication and protection from contaminants. |
| ABEC1 | Defines the precision class, indicating standard tolerance levels for runout and dimensions. |
| MC3 | Specifies the radial internal clearance group (0.002mm to 0.013mm), suitable for most general applications. |
SF625 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and optimized stainless steel cage contribute to a high limiting speed of 32,400 rpm, making it an effective high-speed bearing solution.
- Radial Load Capacity: The deep groove raceway and 7 precision balls provide a dynamic load rating of 298 lbf, ensuring reliable performance under substantial radial stresses.
- Corrosion Resistance & Cleanliness: Full stainless steel construction makes it suitable for harsh environments, washdown applications, and industries requiring ROHS and REACH compliance.
- Precision Engineering: Manufactured to ABEC1 standards with tight dimensional tolerances for smooth, low-vibration operation, contributing to overall system accuracy.
SF625 Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical and Dental Equipment: Used in handheld tools, pumps, and scanners where corrosion resistance and reliability are critical.
- Office Automation: Suitable for high-speed rotors in printers, scanners, and copiers.
- Instrumentation and Control Systems: Provides precise rotation in encoders, gauges, and other sensitive measuring devices.
- Food Processing and Packaging Machinery: Its stainless steel build and cleanability meet hygiene standards for conveyor rollers and mixing equipment.
