S6704 Bearing Product Overview & Core Advantages
The S6704 is a metric single row deep groove ball bearing engineered for precision radial load applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance and reliable performance. Its compact design, with a minimal cross-section, makes it ideal for space-constrained assemblies requiring high precision and durability. The bearing operates effectively across a wide temperature range from -86 to 230 °F and adheres to ABEC-1 tolerance standards, ensuring consistent quality and performance in demanding environments.
S6704 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| S6704 | Basic Model Number | Defines the bearing series and size: 20mm bore, 27mm OD, 4mm width. |
| Open (Seal Type) | No Seals/Shields | Allows for higher limiting speeds and custom lubrication schemes. Requires a clean operating environment. |
| C0 (Radial Clearance) | Normal Internal Clearance | Standard clearance group (0.006mm to 0.020mm), suitable for most general applications. |
| ABEC-1 | Tolerance Class | Specifies standard precision levels for bore, OD, and width tolerances. |
S6704 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making the bearing suitable for washdown environments, medical equipment, and food processing applications.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 7,600 rpm, enabling use in high-speed spindles and small motors.
- Precision Radial Load Support: As a deep groove ball bearing, it is optimized to carry significant radial dynamic load (204 lbf) and radial static load (146 lbf) with minimal friction.
- Compact and Lightweight: With a width of only 4mm and a weight of just 5.9g, this bearing is an optimal solution for miniaturized and weight-sensitive designs without compromising on bearing performance.
S6704 Bearing Typical Application Areas
This precision bearing is commonly specified in:
- Small Electric Motors and High-Speed Spindles
- Medical and Dental Handpieces
- Precision Instruments and Optical Encoders
- Food Processing and Packaging Machinery
- Office Automation Equipment (e.g., printers, scanners)
- Robotics and Miniature Gearboxes
