SF694 Bearing Product Overview & Core Advantages
The SF694 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, with a 4 mm bore and 11 mm outside diameter, makes it ideal for space-constrained, high-precision assemblies requiring reliable performance under moderate loads and speeds.
SF694 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF694 | Basic bearing designation indicating the specific size and internal geometry. |
| Open (Seal Type) | No integral seals or shields, allowing for higher speeds and easy re-lubrication. |
| ABEC1 | Standard precision tolerance class suitable for a wide range of general applications. |
| MC3 | Specifies a normal radial internal clearance group. |
SF694 Bearing Structural Features & Performance Benefits
- High Precision & Stability: The ABEC1 tolerance class and stainless steel construction ensure consistent running accuracy and dimensional stability, critical for sensitive mechanisms.
- Corrosion Resistance: All-stainless-steel build provides excellent protection against rust and corrosion, making it suitable for harsh environments, medical devices, and food processing equipment.
- Optimized Load Capacity: The deep groove raceway and 7-ball design are optimized to handle radial dynamic loads up to 165 lbf efficiently.
- Compact & Lightweight: With a minimal cross-section and a weight of only 1.91 g, it contributes to lightweight and compact designs.
- Standard Internal Clearance: The MC3 radial internal clearance is suited for most common operating conditions and fits.
SF694 Bearing Typical Application Areas
This bearing is commonly specified in:
- Precision Instruments: Optical encoders, measuring devices, and small gauges.
- Small Electric Motors: Miniature DC motors and stepper motors.
- Medical Equipment: Surgical hand tools, dental drills, and pump mechanisms.
- Office Automation: Printers, scanners, and copiers.
- Robotics & Automation: Small joints, guides, and actuators.
