S698 Bearing Product Overview & Core Advantages
The S698 is a high-precision, metric single row deep groove ball bearing engineered for exceptional performance in demanding applications. Constructed entirely from stainless steel, it offers superior corrosion resistance and durability. This bearing is designed to handle primarily radial loads with high efficiency and is characterized by its compact design, featuring an 8 mm bore and a 6 mm width. Its ABEC1 precision class ensures reliable operation, making it an ideal choice for applications requiring consistent performance and long service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S | Stainless Steel construction for corrosion resistance. |
| 6 | Single Row Deep Groove design. |
| 9 | Series designation indicating specific cross-sectional dimensions. |
| 8 | Bore diameter code for an 8 mm bore. |
| (Open) | No seal/shield suffix, indicating an open bearing requiring external lubrication and protection. |
S698 Bearing Structural Features & Performance Benefits
- High-Quality Stainless Steel Construction: The rings, balls, and cage are manufactured from stainless steel, providing excellent resistance to rust and corrosion, which is critical for applications in harsh environments or requiring washdowns.
- Optimized Deep Groove Raceway: The deep groove geometry of the inner and outer rings is designed for efficient radial load handling and moderate axial loads in both directions.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance, this bearing ensures smooth, low-vibration, and low-noise operation, contributing to overall system accuracy.
- High-Speed Capability: With a limiting speed of 32,400 rpm, the S698 is suitable for high-rotation applications. The stainless steel cage and optimized internal geometry contribute to stable operation at high velocities.
- Compact and Lightweight: With a 6 mm width and a weight of only 7.12 grams, it is ideal for space-constrained and weight-sensitive designs.
S698 Bearing Typical Application Areas
- Precision instruments and measuring devices
- Small electric motors and spindles
- Medical and dental equipment
- Food processing and packaging machinery
- Office automation equipment (e.g., printers, scanners)
- Robotics and miniature gearboxes
