S626 Bearing Product Overview & Core Advantages
The S626 metric ball bearing is a precision single row deep groove ball bearing engineered for reliable performance in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads and is characterized by its compact design with a 6 mm bore, 19 mm outside diameter, and 6 mm width. Its ABEC1 precision class ensures consistent operation, making it a dependable choice for applications requiring high reliability and smooth rotation.

| Code Segment | Technical Meaning |
|---|---|
| S | Stainless Steel construction for enhanced corrosion resistance. |
| 6 | Deep Groove ball bearing type. |
| 26 | Indicates the specific bearing dimensions: 6mm bore, 19mm OD. |
| (Open) | No shield or seal, allowing for higher limiting speeds but requiring a protected environment. |
S626 Bearing Structural Features & Performance Benefits
All-Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and suitability for washdown environments or applications exposed to moisture.
Optimized Internal Geometry: The deep groove raceway and six 3.5 mm balls are designed for efficient radial load carrying capacity, with a dynamic load rating of 402 lbf.
High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 28,800 rpm, making it suitable for high-speed applications.
Precision Performance: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), ensuring smooth and quiet operation with minimal vibration.
S626 Bearing Typical Application Areas
The S626 bearing is ideal for a wide range of precision instruments and equipment, including:
- Small electric motors and spindles
- Medical and dental handpieces
- Optical encoders and precision scanners
- Food processing and packaging machinery (where corrosion resistance is critical)
- Radio-controlled models and drones
