SF627 Bearing Product Overview & Core Advantages
The SF627 is a metric single row deep groove ball bearing designed for reliable performance in radial load applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its compact design with a flanged outer ring (25mm OD, 1.5mm thickness) facilitates precise axial location and simplified mounting in housings. This bearing is characterized by its ABEC1 precision class and standard MC3 radial internal clearance, making it a robust and cost-effective solution for various industrial applications requiring consistent operation.
SF627 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF627 | Basic bearing model number, defining the core bearing dimensions (7mm bore, 22mm OD, 7mm width). |
| (No Suffix) | Indicates an open (unsealed) bearing design. Lubrication is required by the user for operation. |
| Flange | Integral flange on the outer ring (25mm diameter) for simplified mounting and positioning. |
SF627 Bearing Structural Features & Performance Benefits
- Stainless Steel Construction: All components (rings, balls, cage) are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments or washdown applications.
- Deep Groove Raceway: The geometry of the deep groove raceway is optimized for handling radial loads efficiently. It can also accommodate moderate axial loads in both directions.
- Flanged Outer Ring: The flange simplifies installation by providing a positive locating surface, reducing assembly time and cost. It also helps to prevent creeping in the housing.
- Precision & Clearance: Manufactured to ABEC1 tolerance class with an MC3 radial internal clearance, ensuring smooth and consistent running performance.
- High-Speed Capability: With a limiting speed of 27,000 rpm, it is suitable for applications requiring high rotational velocities when properly lubricated.
SF627 Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Medical and Dental Equipment
- Food and Beverage Processing Machinery
- Precision Instruments and Optical Devices
- Conveyor System Rollers
- Office Automation Equipment (e.g., Printers, Scanners)
